Rapidly Diversifying Hydrogen‐Bonded Organic Frameworks With Permanent Porosity

Angewandte Chemie, EarlyView.
This article reviews diversifying hydrogen‐bonded organic frameworks (HOFs) with permanent porosity reported over the past 15 years, based on the molecular structures of their constituent tectons. Furthermore, several distinctive aspects and concepts are described, such as permanent porosity, isostructural (isoreticular) HOFs, and multicomponent mixed ...

Boosting Photocatalytic Overall Water Splitting Activity of Phosphorene Through Five‐Coordinate Passivation Enabled by Carbene Addition

Angewandte Chemie, EarlyView.
We report selective five‐coordinate passivation of phosphorene via P═C double bonds using a facile one‐step photochemical reaction via carbene addition. The ambient stability of functionalized phosphorene has been substantially improved compared to the pristine phosphorene.

Reactions of N-heterocyclic carbenes with nitrobenzenes: harnessing NHCs as synthetic building blocks

Journal of Advanced Research
Introduction: Quinazolin-4-one is a privileged scaffold in drugs with broad clinical applications. Conventionally, an o-amino group was generally needed to be pre-installed on the benzoic acid-derived starting materials for the efficient condensation ...

In Situ Amine Formation to Modulate MOF‐Derived PdIn N‐Doped Carbon Catalysts

Advanced Materials, EarlyView.
An amine‐assisted approach converts PdIn‐MOF into PdIn intermetallic nanoparticles embedded in N‐doped carbon. In situ‐generated amines trigger early Pd nucleation, producing smaller PdIn domains than direct pyrolysis. Amine sterics and basicity tune composition and particle size, while solvent and amine co‐determine textural features.

Kinetic‐Directed Thermodynamic Repair Enables the Synthesis of High‐Strain 2D Sub‐Stoichiometric COFs

Advanced Science, EarlyView.
2D covalent organic frameworks are promising photocatalysts. Yet, precise synthesis of sub‐stoichiometric COFs remains challenging due to poor kinetic control. We propose a general strategy: tuning polymerization degree of kinetic intermediates via time or solvent polarity directs their thermodynamic repair into highly crystallization. Using [4+3]‐type
