Summary: Metal-organic frameworks (MOFs), comprised of metal nodes and organic ligands, have attracted significant interest due to their flexible design and intriguing pore structures. However, the applications of MOFs have been limited by their narrow pore size. Hierarchically porous MOFs (HP-MOFs) have been developed to overcome this limitation by combining micropores with meso-/macropores. This review highlights recent advances in the design and synthesis of HP-MOFs with different types of pores, and discusses their applications in various fields.

Summary: In recent years, the synthesis and application of alkenes, particularly triphenylethenes (TriPEs), have gained attention due to their lower molecular torsion and balanced conjugation, resulting in the aggregation-induced emission (AIE) effect. The geometry of double bonds significantly affects luminescence, making it important to provide a comprehensive summary of stereoselective synthetic strategies for trisubstituted alkenes. This review outlines common strategies for stereoselective synthesis, discussing the origin of stereoselectivity and the types of substrates, while also exploring the AIE properties of TriPE and its versatile applications in optoelectronic devices, stimuli-responsive materials, sensors, and therapies.

Summary: Organoboranes are important reagents in synthetic organic chemistry, and their C-B bonds can be transformed into C-X (X=C, N, O, and halogen) bonds stereoretentively to provide valuable complex molecules. Homogeneous transition-metal-catalyzed borylation reactions are effective methods for synthesizing organoboranes, but the inability to recover catalysts and metal contamination in products limits their application. Metal-organic frameworks (MOFs)-based heterogeneous catalytic systems have gained prominence in overcoming these limitations.

Summary: This paper reports an efficient synthesis of alkylboronate esters via the catalysis of copper nanoparticles stabilised on nitrogen-doped carbon nanotubes. The nanocatalyst allows practical access to alkylboronate esters at room temperature in a short time period and exhibits good functional group tolerance. Radical clock experiments suggest that the reaction proceeds through a radical pathway. Additionally, the catalyst can be recycled multiple times without significant loss in activity. Furthermore, the supported copper catalyst is demonstrated to be applicable for the anti-Markovnikov-selective hydroboration of vinylarenes and borylation of aryl halides, providing alkyl- and arylboronate esters with high yields.

Summary: A multicomponent sulfonylation reaction using sulfonyl chlorides and OPiv-supported organozinc reagents was achieved via cobalt-catalyzed alkene difunctionalizations. Anion-coordination played a critical role in modifying the reactivity and chemical properties of organozinc reagents. The OPiv-coordination resulted in the lower reducibility of arylzinc pivalates, allowing for the in situ formation of catalytically relevant Co(I) species as the active catalyst in carbosulfonylation reactions.

Summary: This study presents a novel triarylborane (TB)-dye that serves as both an NMe2 pi-donor and an inductive NMe2-alkyl cationic acceptor. The TB-dye is highly sensitive to a click reaction with an azide-substituted lysine side chain, resulting in a significant red shift of emission. Furthermore, the TB-dye exhibits high affinities towards both DNA and proteins, making it an ideal fluorimetric probe for detecting the progress of click reactions and sensing the binding site composition.
