Summary: In this study, a chromogenic molecular switch with a phenol-phthalein backbone was constructed to visually recognize acetate in pure water. The molecular switch receptor showed good selectivity and binding towards acetate, and the mechanism of acetate recognition was found to involve hydrogen bonding and proton transfer. These findings are expected to contribute to the development of a new class of aqueous anion receptors and molecular recognition mechanisms.

Summary: Host-guest interaction was utilized to create a Eu(III)-based host-guest complex using a quinoline-based tripodal acceptor L-1 with tunable syn and anti-conformers. The complex exhibited host conformation motion and Eu(III)-centered emission enhancement behavior, and could potentially be used as an imaging regent in living cells. Theoretical and experimental data were in good agreement regarding the stabilization of the conformations within the cavity of the tripodal host L-1.

Summary: In this study, the crystal structures of CN--treated [FeFe]-hydrogenase CpI from Clostridium pasteurianum were obtained, revealing that extrinsic CN- binds to the open coordination site of the cofactor. The binding of CN- leads to conformational changes in conserved residues within the proton transfer pathway, potentially facilitating efficient proton transfer. This observation provides important insights into the mechanism of CN- inhibition and proton transfer in hydrogenases.

Summary: The hydrogenation of benzaldehyde to benzyl alcohol is significantly promoted by the presence of polar co-adsorbates like substituted phenols, facilitated by external potential. These co-adsorbates enhance the hydrogenation rate by polarizing the carbonyl group and increasing the likelihood of forming a transition state for H addition, leading to a faster hydrogenation route involving phenol as a conduit for proton addition.

Summary: Inspired by alkaline metal borohydrides and organic-inorganic hybrid perovskite, a complex structure of (CH3NH3)BH4 with high hydrogen capacity is predicted. Through analysis of electronic structures, it is concluded that (CH3NH3)BH4 can be synthesized by a substitution reaction. The structural symmetries, elastic constants, and electronic properties of (CH3NH3)BH4 are investigated, showing strong elastic anisotropy and the influence of a planar dihydrogen bonding network on the dehydrogenation reaction. The proposed dehydrogenation process of (CH3NH3)BH4 via intermediate compounds suggests that it can decompose spontaneously, similar to ammonium borohydride.

Summary: The study reports the self-assembly of a unique molecular container, a hybrid cage combining hydrogen bonding and metal coordination as crucial components of its topology. The hybrid cage, prepared by combining hydrogen-bonded rosette motif and palladium(II)/platinum(II) coordination to a pyridine ligand, shows a genuine dual character for the first time. The dual character is demonstrated as the two self-assembling parts selectively responding to different stimuli, leading to the disassembly of the cage.

Summary: Doped carbon materials, especially F-doped carbon catalysts, have gained significant attention as metal-free catalysts for oxygen reduction reactions and as corrosion-resistant supports for Pt and non-Pt nanoparticles. F-doped carbon materials possess unique properties and greatly improve the activity and durability of the ORR compared to N-doped carbon materials. The high electronegativity of F-doping can efficiently modify the electronic band structure of carbon materials, favoring the ORR. This review systematically discusses the effect of F-doping/F co-doping on the electrocatalytic reduction of O2 in acidic and alkaline conditions, the stability and durability of fuel cell catalysts, and provides guidelines for working with F-doped carbons. Future research directions on F-doped carbons are also proposed to bridge the gap between laboratory-scale assessments and commercial applications.
