Trimerization of 1,2‐Diaminocyclohexane Catalyzed by a Metal–Organic Cage Tandem Catalyst with Dual Biomimetic Active Sites

open access: yesAdvanced Science, EarlyView.
Dual biomimetic active sites, i.e., mononuclear {ZnII(L)(H2O)} and dinuclear {L2ZnII(CHO2)(OH)ZnIIL2}, have been successfully intergrated into a metal–organic cage, Zn20‐MOC. These two different active sites in Zn20‐MOC catalyze different steps of cascade trimerization of 1,2‐diaminocyclohexane. The mononuclear {ZnII(L)(H2O)} site catalyzes the initial

Reductive Supramolecular In Situ Construction of Nano‐Platinum Effectively Couples Cathodic Hydrogen Evolution and Anodic Alcohol Oxidation

open access: yesAdvanced Science, EarlyView.
The supramolecular framework reductant is developed to realize the in situ construction of highly dispersed ultrafine nano‐Pt. The nano‐Pt supported on the BCN carrier realizes multi‐scenario electrocatalytic water hydrogen production, and establish a high‐performance cathode hydrogen evolution‐anode methanol oxidation coupling system, presenting a low‐

Squaraine Dyes for Organic Photomultiplication Photodetectors with 220% External Quantum Efficiency at 1240 nm

open access: yesAdvanced Science, EarlyView.
The synthesis of a range of squaraine dyes is reported with maximum absorption in solution above 1100 nm. Near‐infrared sensitive organic photomultiplication photodetectors are developed. Photomultiplication occurs via squaraine hole trap‐induced injection of electrons from the external circuit.

A Universal Approach to Anchoring Chromophores onto Magnetic Scaffold for Achieving Easily Recyclable Heterogeneous Photocatalytic Systems

open access: yesAdvanced Science, EarlyView.
The practical application of chromophores such as porphyrins, coumarins, anthraquinones, and pyrene derivatives in photocatalysis is severely limited by catalyst stability and reusability. In this work, a simple and universal strategy is presented for preparing highly efficient and recyclable heterogeneous photocatalysts for the oxidative coupling of ...

Dynamic Molecular Cocrystals with Alkyl Chain Dependent Thermosalient Phase Transitions

open access: yesAdvanced Science, EarlyView.
A series of cocrystals containing 5‐fluorocytosine and fatty acids with varying alkyl chain lengths are synthesized, demonstrating a systematic modulation of thermosalient phase transition temperatures across a broad range (≈100 K). This study reveals a linear correlation between interlayer hydrophobic interactions and transition temperatures, offering
