Carboxylic Anhydride Linkers (1536)

Carboxylic anhydride linkers, characterized by two bonded carbonyl groups, serve as functional groups for constructing covalent organic frameworks (COFs) through condensation reactions. These linkers enhance the thermal and chemical stability of COFs, making them well-suited for demanding environments and extreme conditions. COFs incorporating carboxylic anhydride linkers demonstrate exceptional gas separation capabilities, attributed to their precise control over pore size and surface chemistry. Such COFs find applications in membrane technology, where their remarkable selectivity and permeability are ideal for gas separation and purification processes. The adaptability of carboxylic anhydride linkers enables the synthesis of COFs with customizable pore structures and functionalities, allowing fine-tuned control over material properties and performance.
