--Electrochemical Transformation of CO2. CO2 is not only a main greenhouse gas, but it is also a low-cost, abundant, non-toxic, and renewable C1 feedstock. Electrochemical transformation of CO2 to value-added chemicals and fuels is a promising route to reduce CO2 emission and contribute to sustainability and carbon neutrality. In this Mini Review, Xiaofu Sun, Buxing Han, and coworkers review recent developments in methods for electrochemical transformation of CO2 and discuss future challenges.

-Molecular-Strain Engineering. Trapping unstable intermediates for elucidating reaction mechanisms in chemistry remains a significant challenge. Zhichang Liu and coworkers report a molecular-strain engineering (MSE) strategy that harnesses intramolecular strain to trap native phlorin during porphyrin synthesis. The MSE strategy may offer a convenient way of investigating mechanisms in synthesis and catalysis.

-Detection of Organic Mixtures. Although luminescence sensing of a chemical substance is one of the most commonly used detection methods, simultaneous and quantitative detection of several components in a mixture is difficult. Wei Shi and coworkers develop a triple emission material by introducing Eu3+ and Tb3+ ions into the pores of a blue-emitting metal–organic framework. The luminescence responses of multiple emission centers enable the rapid determination of the concentrations of three isomers in several mixtures.

-Zero-Compressible Materials. Materials with zero linear compressibility (ZLC) and zero-area compressibility (ZAC) have great promise for specific applications requiring constancy in specific directions or planes in extreme environments. Ting Wen, Yong gang Wang, and coworkers report intrinsic ZLC and ZAC properties of Li2Ti(IO3)6 with a gear-spring type structure over an ultrawide pressure range (0–40 GPa).

-Catalyst-Free Regioselective Hydroacylation. Huiying Zeng, Chao-Jun Li, and coworkers have developed a base-promoted regioselective hydroacylation of styrenes using hydrazones as acylation reagent via carbanion addition. This reaction proceeds smoothly in the absence of transition metals and chelating groups to form linear ketones under mild conditions. In addition, their protocol can tolerate various functional groups, providing an alternative approach to transition metal catalyzed hydroacylation.

-Stable Perovskite Materials. The stability of perovskite precursor solutions is a crucial factor in the commercialization of solution-processed perovskite-based optoelectronic devices. Yonghua Chen and coworkers reveal the formation mechanism and microscopic structure of chemically robust perovskite precursor solutions prepared by using methylammonium acetate as the solvent. Moreover, various perovskite precursors display significantly higher stability in methylammonium acetate than in the traditional DMF/DMSO solvent.

-Nanocatalysts for Selective Hydrogenation. Nanocatalysts often encounter problems with aggregation and leaching-induced degradation of catalytic activity. Guangqin Li and coworkers report a facile method to encapsulate alloy-nanoparticle (NP)-loaded metal–organic framework (MOF) catalysts (alloy NPs/MOFs). A series of PtM/MOFs (M = Fe, Co, and Ni) catalysts are successfully synthesized and demonstrate an enhanced catalytic performance toward selective hydrogenation reaction.

-Antibacterial Supramolecular Polymers. Jiang-Fei Xu and coworkers fabricate an NIR photothermal antibacterial agent through Escherichia coli reduction-powered in situ supramolecular polymerization. Because of the unique reducing ability of E. coli to generate viologen cation radicals and local enrichment of the supramolecular dimer of viologen cation radicals by supramolecular polymerization, the agent exhibits outstanding antibacterial activity with high specificity towards E. coli in NIR-II photothermal therapy.

-Single-Atom Catalysts. Linear scaling relations are powerful for predicting the performance of traditional metal catalysts, but they fail in the case of single-atom catalysts (SACs). Jun Li, Ning Yan, and coworkers present one of the first successful approaches for reestablishing scaling relations for catalytic reactions by SACs with potentially broad implications for catalytic processes actively involving this support.

-Rare-Earth Metal Catalysts. Qian Peng, Yaofeng Chen, and coworkers have found that a lutetium phosphino-phosphinidene complex, with Lu=P double-bond character, is able to catalyze the hydrogenation of terminal alkenes under mild conditions. They confirm that the catalytic reaction proceeds through an addition/elimination mechanism rather than the traditional σ-bond metathesis mechanism.

-CO2 Electroreduction. Although great progress has been made in electrochemically converting carbon dioxide (CO2) to liquid fuels, there remains a demand to understand the mechanisms and find efficient methods to guide the design of highly-selective electrocatalysts. Ping-Ping Fang, Jian-Qiang Hu, Jian-Feng Li, and coworkers use operando Raman spectroscopy combined with density functional theory calculations to reveal mechanisms that explain why sulfurization can greatly improve ethanol selectivity for CO2 electroreduction.

-Light-Driven Ion Transport. Wei Guo and coworkers have successfully demonstrated a bidirectional light driven ion transport phenomenon through a porphyrin metal–organic framework (PMOF) and WS2 reassembled van der Waals heterostructures. The light-driven ionic flow can be made to fully switch directions by simply altering the environmental pH. Anticipated applications include photonic–ionic circuits for neuromorphic computing and artificial photosynthesis.

-Catalytic Asymmetric Synthesis. Zhi-Min Chen and coworkers have successfully developed chiral sulfide/phosphoric acid cocatalyzed enantioselective intermolecular oxysulfenylations of alkenes with phenols and alcohols as O-nucleophiles. A variety of sulfur-containing benzylic aryl ethers and benzylic alkyl ethers, which contain two contiguous chiral stereocenters, are readily obtained in moderate to excellent yields with high to excellent enantioselectivities.

-Cysteine-Specific Bioconjugation. Huan Wang and coworkers demonstrate that chlorooxime derivatives are cysteine-specific peptide bioconjugation and stapling reagents that generate stable thiohydroximate linkages. The high reactivity and chemoselectivity of chlorooximes toward cysteine may support their application in constructing a cyclic peptide library.

-Luminescent Metal Clusters. Liang Zhao, Siqi Zhang, and HanWu synthesize a series of discrete spirocyclic Ag9 clusters with varying lengths of alkyl chains that exhibit distinct assembling behaviors in response to varying the concentration, temperature, and solvent polarity in solution. The assembly of silver clusters not only generates emission enhancement but also gives rise to intriguing mechano- and vapochromic luminescent properties.

-Collective Total Synthesis. Although the classical Ritter reaction has been widely applied to prepare sterically hindered amides, it has intrinsic problems including harsh reaction conditions. Fu-Min Zhang and coworkers develop a novel oxidative Ritter-type reaction with mild conditions for broad scopes, which can be used to efficiently synthesize many challenging amides bearing N-acyl aza-quaternary carbon centers.

-Multicomponent Polymerization. Chiral polymers with metal-coordination ability show great potential for mediating asymmetric reactions. However, the synthesis of structurally diverse chiral polymers remains a great challenge. Wangze Song, Nan Zheng, and coworkers develop four types of Cu-catalyzed multicomponent asymmetric polymerizations for the synthesis of a series of poly-triazolyl-methanamines with desired molecular weights and well-defined chiral structures. The chiral poly-triazolyl-methanamines outperform commercially available chiral ligands in mediating asymmetric reactions.

-Metal–Organic Frameworks. The similarities in molecular size and physical properties of acetylene (C2H2) and carbon dioxide (CO2) create a formidable challenge when separating the two species. Qing-Yan Liu and coworkers develop two robust trinuclear cluster-based metal–organic frameworks featuring distinctive nanosized cage-within-cage structures and highly polarized and fluorophilic pore environments, which show a record capture for C2H2 and high performance for C2H2/CO2 separation.

- Supramolecular Polymer Chemistry. Xiao-Yu Hu and coworkers have constructed a chiral host–guest complex donor system for chiral amplification via induced chirality of pillar[5]arene host and loaded it with an achiral dye acceptor. They demonstrate how chirality-assisted excitation energy transfer occurs in the supramolecular nanohelix system in an aqueous medium. The proposed multichannel chirality transfer system provides a new avenue for developing various chiroptical materials with diverse functionality.
