Abstract: A photoredox-catalyzed and copper-promoted trifluoromethoxylation of arenediazonium tetrafluoroborates ha-ve been developed for the first time. Trifluoromethyl arylsulfonate (TFMS) was used as the trifluoromethoxylation reagent. This reaction is scalable and proceeds regioselectively under mild reaction conditions. Furthermore, mechanistic studies suggested that Cs[Cu(OCF3)2] intermediate might be generated during the reaction.

ABSTRACT: While remarkable progress has been made over the past decade, new design strategies for chiral catalysts in enantioselective C(sp3)−H functionalization reactions are still highly desirable. In particular, the ability to use attractive non-covalent interactions for rate acceleration and enantiocontrol would significantly expand the current arsenal for asymmetric metal catalysis. Herein, we report the development of a highly enantioselective Ir(III)-catalyzed intramolecular C(sp3)−H amidation reaction of dioxazolone substrates for synthesis of optically enriched g-lactams using a newly designed a-amino acid-based chiral ligand. This Ir-catalyzed reaction proceeds with excellent efficiency and with outstanding enantioselectivity for both activated and unactivated alkyl C(sp3)−H bonds under very mild conditions. It offers the first general route for asymmetric synthesis of g-alkyl g-lactams. Water was found to be a unique co-solvent to achieve excellent enantioselectivity for g-aryl lactam production. Mechanistic studies revealed that the ligands form a well-defined groove-type chiral pocket around the Ir center.The hydrophobic effect of this pocket allows facile stereo-controlled binding of substrates in polar or aqueous media. Instead of capitalizing on steric repulsions as in the conventional approaches, this new Ir catalyst operates through an unprecedented enantiocontrol mechanism for intramolecular nitrenoid C−H insertion featuring multiple attractive non-covalent interactions.

Abstract

Until now, materials with high elasticity at deep cryogenic temperatures ha ve not been observed. Previous reports indicated that graphene and carbon nanotube–based porous materials can exhibit reversible mechano-elastic beha vior from liquid nitrogen temperature up to nearly a thousand degrees Celsius. Here, we report wide temperature–invariant large-strain super-elastic beha vior in three-dimensionally cross-linked graphene materials that persists even to a liquid helium temperature of 4 K, a property not previously observed for any other material. To understand the mechanical properties of these graphene materials, we show by in situ experiments and modeling results that these remarkable properties are the synergetic results of the unique architecture and intrinsic elastic/flexibility properties of individual graphene sheets and the covalent junctions between the sheets that persist even at harsh temperatures. These results suggest possible applications for such materials at extremely low temperature environments such as those in outer space.

Abstract
Regioselective hydroboration of aliphatic internal alkenes remains a great challenge. Reported here is an iridium‐catalyzed hydroboration of aliphatic internal alkenes, providing distal borylated products in good to excellent yields with high regioselectivity (up to 99:1). We also demonstrated that the C‐B bond of the distal borylated product could be converted facilely to other functionalities. DFT calculation indicated that reaction undergoes an unexpected Ir(III/V) cycle.

Device performance and in particular device stability for blue perovskite light-emitting diodes (PeLEDs) remain considerable challenges for the whole community. In this manuscript, we conceive an approach by tuning the ‘A-site’ cation composition of perovskites to develop blue-emitters. We herein report a Rubidium-Cesium alloyed, quasi-two-dimensional per- ovskite and demonstrate its great potential for pure-blue PeLED applications. Composition engineering and in-situ passivation are conducted to further improve the material’s emission property and stabilities. Consequently, we get a prominent film photoluminescence quantum yield of around 82% under low excitation density. Encouraged by these findings, we finally achieve a spectra-stable blue PeLED with the peak external quantum efficiency of 1.35% and a half-lifetime of 14.5 min, representing the most efficient and stable pure-blue PeLEDs reported so far. The strategy is also demonstrated to be able to generate efficient perovskite blue emitters and PeLEDs in the whole blue spectral region (from 454 to 492 nm).

Abstract

Even though the general mechanism of photodynamic therapy for cancer is known, the details and consequences of the reactions between the photosensitizer generated singlet oxygen and substrate molecules remain elusive at the molecular level. Using temoporfin as the photosensitizer, here we combine field‐induced droplet ionization mass spectrometry and acoustic levitation techniques to study the “wall‐less” oxidation reactions of 18:1 cardiolipin and POPG mediated by singlet oxygen at the air‐water interface of levitated water droplets. For both cardiolipin and POPG, every unsaturated oleyl chain is oxidized into an allyl hydroperoxide, which surprisingly is immune to further oxidation. This is attributed to the increased hydrophilicity of the oxidized chain, attracting it toward the water phase, increasing membrane permeability and eventually triggering cell death.

Abstract

Ultrathin 2D nanomaterials possess promising properties due to electron confinement within single or a few atom layers. As an emerging class of functional materials, ultrathin 2D rare‐earth nanomaterials may incorporate the unique optical, magnetic, and catalytic beha-viors of rare‐earth elements into layers, exhibiting great potential in various applications such as optoelectronics, magnetic devices, transistors, high‐efficiency catalysts, etc. Despite its importance, reviews on ultrathin 2D rare‐earth nanomaterials or related topics are rare and only focus on a certain family of ultrathin 2D rare‐earth nanomaterials. This work is the first comprehensive review in this impressive field, which covers all families of ultrathin 2D rare‐earth nanomaterials, illustrating their compositions, syntheses, and applications. After summarizing the current achievements, the challenges and opportunities of future research on ultrathin 2D rare‐earth nanomaterials are evaluated.

Abstract
Bifunctional Au@Ni core‐satellite nanostructures synthesized via a one‐step assembling method are employed for in situ surface‐enhanced Raman spectroscopic (SERS) monitoring of Ni‐catalyzed C‐C bond‐forming reactions. Surprisingly, the reaction which was thought to be an Ullmann‐type self‐coupling reaction, is found to be a cross‐coupling reaction proceeding via photo‐induced aromatic C‐H bond arylation. According to the discovery enabled by the in situ SERS monitoring, a series of biphenyl compounds are synthesized at room temperature by photocatalytic reaction using the cheap Ni NP catalysts.

Abstract


This review details the emergence and continued study of the template effect in metal-organic frameworks (MOFs) with emphasis upon (i) reports of template-directed synthesis of MOFs and (ii) using MOFs as hosts to template the formation of new guest species. We focus herein on the relationship between the pore environments of MOF hosts and their guests, and the resulting host-guest properties. Such understanding can enable template effects to serve as a supplementary tool of crystal engineering since it can afford new and otherwise unattainable MOF structures. Templating can also result in control over the chemical reactivity of guests through an enzymatic like process. We also address emerging applications of MOFs formed through a template effect. We anticipate that this review will provide a guide for future research into preparing functional MOFs with targeted structures or properties and to generate reaction products using MOFs as templates.

Abstract
Programmable self‐assembly of peptides into well‐defined nanostructures represents one promising approach for bioinspired and biomimetic synthesis of artificial complex systems and functional materials. Despite the progress made over the past two decades in the development of strategies for precise manipulation of the self‐assembly of peptides, there is a remarkable gap between current peptide assemblies and biological systems in terms of structural complexity and functions. Here, the concept of peptide tectonics for the creation of well‐defined nanostructures predominately driven by the complementary association at the interacting interfaces of tectons is introduced. Peptide tectons are defined as peptide building blocks exhibiting structural complementarity at the interacting interfaces of commensurate domains and undergoing programmable self‐assembly into defined supramolecular structures promoted by complementary interactions. Peptide tectons are categorized based on their conformational entropy and the underlying mechanism for the programmable self‐assembly of peptide tectons is highlighted focusing on the approaches for incorporating the structural complementarity within tectons. Peptide tectonics not only provides an alternative perspective to understand the self‐assembly of peptides, but also allows for precise manipulation of peptide interactions, thus leading to artificial systems with advanced complexity and functions and pa ves the way toward peptide‐related functional materials resembling natural systems.

Abstract

Folding and unfolding are essential ways for a protein to regulate its biological activity. The misfolding of proteins usually reduces or completely compromises their biological functions, which eventually causes a wide range of diseases including neurodegeneration diseases, type II diabetes, and cancers. Therefore, materials that can regulate protein folding and maintain proteostasis are of significant biological and medical importance. In living organisms, molecular chaperones are a family of proteins that maintain proteostasis by interacting with, stabilizing, and repairing various non‐native proteins. In the past few decades, efforts ha ve been made to create artificial systems to mimic the structure and biological functions of nature chaperonins. Herein, recent progress in the design and construction of materials that mimic different kinds of natural molecular chaperones is summarized. The fabrication methods, construction rules, and working mechanisms of these artificial chaperone systems are described. The application of these materials in enhancing the thermal stability of proteins, assisting de novo folding of proteins, and preventing formation of toxic protein aggregates is also highlighted and explored. Finally, the challenges and potential in the field of chaperone‐mimetic materials are discussed.

Abstract

Aqueous zinc-ion batteries (ZIBs) are considered as the promising energy storage devices for large-scale energy storage systems due to their high safety and low cost. In recent years, various vanadium-based compounds ha-ve been widely developed to serve as the cathodes of aqueous ZIBs because of their low cost and high theoretical capacity. Furthermore, different energy storage mechanisms are observed in the ZIBs based on vanadium-based cathodes. In this minireview, we present the comprehensive overview of the energy storage mechanisms and structural features of various vanadium-based cathodes in ZIBs. Furthermore, we discuss the strategies for improving the electrochemical performance of vanadium-based cathodes, including insertion of metal ions, adjustment of structural water, selection of conductive additives and optimization of electrolytes. Finally, this minireview also offers insights regarding the potential future directions in the design of innovative vanadium-based electrode materials.

Abstract  

We reveal a unique broadband natural quasi-phase-matching (QPM) mechanism underlying an observation of highly efficient second- and third-order harmonic generation at multiple wa velengths in an x-cut lithium niobate (LN) microdisk resonator. For light wa ves in the transverse-electric mode propagating along the circumference of the microdisk, the effective nonlinear optical coefficients naturally oscillate periodically to change both the sign and magnitude, facilitating QPM without the necessity of domain engineering in the micrometer-scale LN disk. The second-harmonic and cascaded third-harmonic wa ves are simultaneously generated with normalized conversion efficiencies as high as 9.9%/mW and 1.05%/mW2, respectively, thanks to the utilization of the highest nonlinear coefficient d33 of LN. The high efficiency achieved with the microdisk of a diameter of ∼30  μm is beneficial for realizing high-density integration of nonlinear photonic devices such as wa velength convertors and entangled photon sources.

ABSTRACT: Enantioselective transition-metal-catalyzed carbene insertion into Si–H bonds is a promising method for preparing chiral organosilicons; however, all the carbene precursors used to date in this reaction ha ve been diazo compounds, which significantly limits the structural diversity of the resulting chiral organosilicons. Herein, we report a protocol for rhodium-catalyzed asymmetric Si–H bond insertion reactions that use functionalized alkynes as carbene precursors. With chiral dirhodium tetracarboxylates as catalysts, the reactions of carbonyl-ene-ynes and silanes smoothly ga ve chiral organosilanes in high yields (up to 98%) with excellent enantioselectivity (up to 98% ee). Kinetic studies suggest that insertion of the in situ generated rhodium carbenes into the Si–H bonds of the silanes is probably the rate-determining step. This work represents the first enantioselective Si–H bond insertion reaction using alkynes as carbene precursors and opens the door for preparing chiral organosilicons with unprecedented structural diversity from readily a vailable alkynes.

KEYWORDS: Asymmetric synthesis, chiral organosilicons, rhodium carbenes, Si–H bond insertion, alkynes

Abstract

Simultaneous removal of trace amount of propyne and propadiene from propylene is an important but challenging industrial process. In this study, we reported a class of microporous metal‐organic frameworks (NKMOF‐1‐M) with exceptional water stability and remarkably high uptakes for both propyne and propadiene at low pressures. Attributed to the strong bind affinity to propyne and propadiene over propylene, NKMOF‐1‐M created new benchmark selectivities for ternary propyne/propadiene/propylene (0.5/0.5/99.0) mixture, and set as a unique MOF platform to achieve both the highest selectivity and productivity of polymer‐grade propylene (99.996%) at ambient temperature, verified by both simulated and experimental breakthrough results. Moreover, we demonstrated a rare example to visualize propyne and propadiene molecules in the single‐crystal structure of NKMOF‐1‐M through a convenient approach under ambient condition, which helped to precisely understand the binding sites and affinity of propyne and propadiene. These results provide important guidance on using ultramicroporous MOFs as physisorbent materials to resolve industrial challenges related to ternary propyne/propadiene/propylene mixture separation.

Summary

MRI contrast agents (CAs) feature coordinated water molecule(s) (aqua ligands), which renders them unsuitable for magnetic resonance (MR) temperature mapping because of their resulting sensitivity to metabolic and physiological changes and/or their tendency to release toxic Gd3+ cations. Herein, we introduce an approach to temperature mapping based upon a coordinatively saturated gadolinium (Gd)-based metal-organic framework (MOF) that exhibits enhanced proton relaxation and high temperature sensitivity. The stable, non-toxic Gd zeolite-like MOF Gd-ZMOF was observed to generate a large enhancement in contrast as a result of a large (70%) contribution from second-sphere water relaxivity. Temperature mapping by clinical CAs and Gd-ZMOF by means of longitudinal (T1) relaxivity was investigated. Gd-ZMOF enabled the visualization of small temperature changes, especially in the thermal therapy region (41°C–45°C). In vivo thermal imaging demonstrates the feasibility of Gd-ZMOF as an MR thermometer and as a potential theranostic.
