-Covalent Organic Framework Electrode Materials. Given the many shortcomings of traditional electrode materials in alkali metal-ion batteries (AIBs), covalent organic framework (COF) electrode materials are becoming increasingly important for the study of large-scale energy storage systems. In this mini-review, Qichun Zhang（张其春）, Xiaosi Zhou（周小四）, and coworkers discuss some structures, designs, and advantages of using COF electrode materials for AIBs. They also present challenges and guidelines for further development of these materials and their design for use in AIBs.

-Reversible CO2 Uptake. The capture, storage, and release of CO2 are some of the most pressing issues in chemistry. Peter W. Roesky and coworkers disclose the reaction of a bis(formazanate) magnesium complex with CO2 that results in a formazanate carbamato complex with a trinuclear cage-like structure. The insertion of CO2 into the Mg–N bonds is reversible depending on thermolysis or treatment with tetrahydrofuran and presents the first example of reversible uptake of CO2 by an s-block coordination compound.

-Analyses Inside Single Cells. The chemically modified solid-phase nanoelectrode has been a well-developed tool for the analysis of biomolecules in single living cells. However, due to the limit of assay elements modified at the solid surface, challenges in increasing the analyte type and the detection sensitivity remain. Rongrong Pan（潘荣容）, Dechen Jiang（江德臣）, and coworkers have designed a novel liquid-phase modified nanopipette to achieve real-time and local analysis of biomolecules inside the cell that are hardly detected using solid-phase modified nanoelectrodes. With a high spatial-resolution of 70 nm, the new nanopipette can be used to reveal the uneven distribution of biomolecules in single living cells.

-Asymmetric Olefin Isomerization. Yu Lan （蓝宇）, Qiang Liu（刘强）, and coworkers disclose a highly efficient protocol for a desymmetric olefin isomerization reaction to construct remote all-carbon quaternary stereocenters by using an optimized chiral cobalt catalyst. A number of enantioenriched 1-methylcyclohexenes can be obtained in high yields with excellent chemo-, site-, and stereoselectivites. Furthermore, the gram-scale synthesis and stereoretentive transformations of spirocyclic products demonstrate the synthetic utility of this reaction.

-Photo-Control of Protein Function. Genetic encoding of photocaged noncanonical amino acids provides a powerful tool to study protein functions through optical control, but it is not yet available for acidic amino acids. Tao Liu（刘涛） and coworkers report the first site-specific genetic encoding of photocaged glutamate into recombinant proteins via an expanded genetic code through evolved EcLeuRS/tRNA pairs. This general method provides photo-control protein activity based on caging a critical glutamate.

-Li-Ion Batteries. It is well-known that charging of Li-ion batteries (LIBs) is accompanied by volume expansion, an indicator of capacity fading and structural failure. Wei Wang（王伟） and coworkers develop an optical volumography technique to precisely determine the volume of a commercial cylindrical LIB cell by taking a series of photos and reconstructing its 3D surface profile. The volume changes during charge–discharge cycling can be monitored in real time at a sensitivity of 1 × 10−5 (ΔV/V0).

-Conjugated Polymers for Solar Cells. Qinghe Wu（武庆贺） and coworkers design thienoacenaphthopyrazine-based monomers and construct two semiconducting polymers which have unique geometry with large fused aromatic rings perpendicular to the polymer chain. By using a suitable electron acceptor, they found that the polymeric organic solar cell exhibits the highest efficiency of 17.14%. This design strategy opens a new avenue for the development of high-performance polymer donors.

-Conformation-Modulated Reactivity. Qizhao Li（李其兆）, Hiroyuki Furuta, and coworkers report that the oxidative dimerization of a thia-hydrosapphyrin yields an anti-dimer and a syn-dimer comprised of a transoid-oriented plate-like bipyrrolo[1,2-a]indolylidene. Notably, the anti-dimer readily undergoes subsequent oxidative fusion to furnish an octacyclic compound, whereas the syn-dimer cannot be further fused. Their study highlights the importance of conformation-modulated reactivity for constructing complex porphyrin arrays.

-Organic Radical Anions. Xinping Wang（王新平）, Chuang Zhang（张闯）, and De-Xian Wang（王德先） present the efficient syntheses, crystal structures, and physical properties of a series of novel benzene triimide (BTI) radical anions. The C3-symmetric BTI backbone provides a useful molecular platform for abundant substitutions which endow novel anion radicals structural tunability and versatile physical properties. π-pimers and π-stacks with effective charge transport exhibit paramagnetic property and conductivity feasibly at room temperature, while π-dimers and π-trimers featuring thermally populated spin-triplet states are antiferromagnetic and nonconductive due to their strong radical–radical pairing effect.

-Synthesis of P,S Ligands. Jian Xu, Qiuling Song（宋秋玲）, and coworkers develop a new method for the synthesis of ortho-sulfurated arylphosphanes via phosphonothiolation of arynes with P(O)H and elemental sulfur. This method avoids the use of transition metal catalysts and corrosive phosphorus chloride. Importantly, the reaction can greatly extend the diversity of phosphine ligand libraries for ligand optimization in cross-coupling reactions.

-Mechanochemistry of Rotaxanes. The mechanochemistry of rotaxanes has attracted great attention in recent years, and all reported examples of rotaxane based mechanophores are focused on locating the stress to the mechanical linkage by pulling on the axle and macrocycle. Yan Xia （夏岩）and Jinghui Yang have developed an innovative design where stretching the macrocycle of the rotaxane leads to selective disassembly and release of the encircled guest molecule. Such a rotaxane design can offer a modular and versatile platform for mechanically releasing functional molecules.

-Asymmetric Hydrogenation of Indoles. Transition metal-catalyzed asymmetric hydrogenation of indoles has been applied to alkyl-substituted unprotected indoles. However, catalytic hydrogenation of the aryl-substituted unprotected indoles is unsatisfactory in reactivity or enantioselectivity. Xumu Zhang（张绪穆）, Xiu-Qin Dong（董秀琴）, and coworkers develop a highly efficient Ir/bisphosphine-thiourea ligand ZhaoPhos catalytic system for asymmetric hydrogenation of aryl-substituted unprotected indoles. A wide variety of chiral indoline derivatives is obtained in good to high yields with excellent stereoselectivities.

-Site-Selective Protein Modification. By employing a proximity-triggered strategy, Dongyuan Wang, Feng Yin (尹丰), Zigang Li(李子刚), and coworkers develop a site-selective group transfer reaction by selectively installing different functional groups onto a specified cysteine in a target protein, such as epidermal growth factor receptor. The technique can be used for different purposes, including cell imaging, protein profiling, and targeted protein degradation. They have merged the fields of site-selective protein modification and targeted protein degradation for the first time with a group transfer strategy.

-Metal–Organic Frameworks. Xinchen Kang（康欣晨）, Buxing Han（韩布兴）, and coworkers report a novel route to the syntheses of various metal–organic frameworks (MOFs) in a radical solution at room temperature with no external energy input. The 1-octyl-3-methylimidazolium radicals in the solution greatly accelerate the coordination between metal ions and ligands, leading to rapid kinetics of MOF formation. This radical-assisted strategy may be applied in other reactions and material fabrication approaches.

-Photocatalytic H2 Production. Yu Li（李昱）, Can Li（李灿）, Bao-Lian Su（苏宝连）, and coworkers report novel and bio-inspired electron donor pairs offering a noncyclic electron transfer pathway which provides more electrons without the consumption of the photo-generated electrons. Compared to the state-of-the-art electron donor pair Na2S-Na2SO3, these novel Na2S-NaH2PO2 and Na2S-NaNO2 electron donor pairs enable an unprecedented enhancement of average photocatalytic H2 production up to 370% and 140% over commercial CdS nanoparticles for visible-light water splitting. Their approach is a major step towards industrialized photocatalytic H2 production.
