Three-Dimensional Covalent Organic Framework for the Capture of Nitrogen Dioxide

Abstract We report the first adsorption isotherm of nitrogen dioxide (NO2) in covalent organic frameworks (COFs). Leveraging the dihedral angle (43.6°) of the biphenyl unit in biphenyl-3,3′,5,5′-tetracarbaldehyde, upon reaction with p-phenylenediamine, a three-dimensional COF, PK...

Aromaticity Regulation in Isostructural Metal‐Organic Frameworks for Propyne Storage and Propylene Purification

ABSTRACT We report the exceptional propyne (C 3 H 4 ) storage and propylene (C 3 H 6 ) purification in a metal‐organic framework, PKU‐101, controlled via regulation of aromaticity. The pyrene‐fused pore interior of PKU‐101 provides multiple C─H···π interactions for alkyne, result...
