Engineering Polar Nanoregions in COFs via Controlled Symmetry Breaking Toward Piezocatalysis

Angewandte Chemie, EarlyView.
Polar nanoregions (PNRs) are engineered within covalent organic frameworks via asymmetric grafting of highly polar polyfluoroalkyl chains, which enables controlled symmetry breaking. These randomly oriented artificial PNRs dynamically respond to mechanical stimuli and impart relaxation behavior to the COFs (TFB‐TAPT‐FA).

Linker‐Locking Strategy for the Rigidification of Flexible Metal–Organic Framework: Structural Stabilization and Controlled ESIPT for H2O/D2O Sensing

Advanced Science, EarlyView.
A linker‐locking strategy rigidifies the flexible metal–organic framework (MOF) MIL‐53‐(OH)2 via the cooperative encapsulation of ligands and structural water. This network significantly enhances the framework's aqueous stability. Crucially, rigidification suppresses enol emission to yield a single keto tautomer state with an extended lifetime ...

Comparison of the Saturated Salt Solution and the Dynamic Vapor Sorption techniques based on the measured sorption isotherm of barley straw

, 2017
International audience9 For Heat, Air and Moisture modelling, one of the most crucial hygrothermal properties of porous 10 construction materials is the sorption isotherm. Current techniques for measuring the sorption 11 isotherm rely on the standardized

Rare‐Earth Multivariate Metal–Organic Frameworks: Cationic Radius Biased Compositional Control and Property Tuning

Angewandte Chemie, EarlyView.
A family of multivariate metal–organic frameworks, UoB‐116(Ln), can be prepared using up to 16 different metals, revealing the ability to tune properties through compositional control. ABSTRACT The synthesis of a multivariate metal–organic framework (MTV‐MOF) family, [Ln(DNNDI)1.5]n (UoB‐116), is reported (DNNDI: N,N'‐bis(dinicotinate)‐1,4,5,8 ...

Engineering an Artificial Metalloenzyme for Efficient Photo‐Enzymatic CO2 Conversion

Advanced Science, EarlyView.
We built a light‐driven artificial metalloenzyme by covalently conjugating formate dehydrogenase (FDH) with a tailored rhodium complex (Rh‐L6) to overcome spatial‐separation‐limited electron transfer. This integration boosts NADH regeneration and CO2 conversion, giving 2.31‐fold higher formate yield than physical mixtures, due to a narrowed bandgap and
