Carboxylic Anhydride Linkers (1536)

Carboxylic anhydride linkers, characterized by two bonded carbonyl groups, are functional groups employed in the synthesis of covalent organic frameworks (COFs) through condensation reactions. These linkers enhance the thermal and chemical stability of COFs, making them well-suited for operation in harsh environments and extreme conditions. COFs incorporating carboxylic anhydride linkers often demonstrate exceptional gas separation capabilities, attributed to the precise control over pore size and surface chemistry. Such COFs find applications in membrane technology, where their high selectivity and permeability are advantageous for gas separation and purification. The adaptability of carboxylic anhydride linkers facilitates the creation of COFs with customized pore structures and functionalities, enabling meticulous control over material properties and performance.
