Abstract

Abstract : Integration of a building block that interacts only weakly with CO2 to the backbone of covalent organic frameworks reveals profound collective effects on facilitating CO2 uptake and separation. Abstract : Covalent organic frameworks are designed to have backbones with different yet discrete contents of triarylamine units that interact weakly with CO2 . Adsorption experiments indicate that the triarylamine units dominate the CO2 adsorption process and the CO2 uptake increases monotonically with the triarylamine content. These profound collective effects reveal a principle for designing backbones targeting for CO2 capture and separation.
