n -Butane Capture Accompanied by a Colorimetric Response in a Flexible Thiazolothiazole Metal–Organic Framework

Szymon K. Sobczak, Asif Raza, Bartosz Mazur, Wola Mishchanka et autres

Abstract Simultaneous capture and optical detection of flammable gases in enclosed environments are critical for operational safety. Herein, using two dynamic MOFs, UAM-1S and UAM-1O, which differ compositionally by a single atom, we demonstrate the crucial role of framework flexibility in enabling …

Peristaltic Motion in Structurally Adaptive Molecular Crystals Enables Selective Propyne Capture

Y. K. Lin, Hayden A. Evans, Asif Raza, Sousa Javan Nikkhah et autres

Cyclotetrabenzoin and its tetraacetate, two macrocyclic porous molecular crystals, were examined as adsorbents for light hydrocarbons, with a focus on C 3 hydrocarbons: propane, propene, and propyne. While both materials exhibit a preference for propyne, only the tetraacetate─owing to its higher surface …

An ionic ultramicroporous polymer with engineered nanopores enables enhanced acetylene/carbon dioxide separation

Asif Raza, Sousa Javan Nikkhah, Lilia Croitor, Ahmed G. Attallah et autres

Ionic ultramicroporous polymers are compositionally fine-tuned. Extending the cationic arm in a new variant is found to double the acetylene over CO 2 adsorption selectivity, underpinned by detailed computational studies on the binding sites.

Downsizing Porphyrin Covalent Organic Framework Particles Using Protected Precursors for Electrocatalytic CO 2 Reduction

Kenichi Endo, Asif Raza, Liang Yao, Samuel Van Gele et autres

Abstract Covalent organic frameworks (COFs) are promising electrocatalyst platforms owing to their designability, porosity, and stability. Recently, COFs with various chemical structures are developed as efficient electrochemical CO 2 reduction catalysts. However, controlling the morphology of COF catalysts remains a challenge, which …
