Constitutional isomerism of the linkages in donor–acceptor covalent organic frameworks and its impact on photocatalysis

Constitutional isomerism of the linkages in donor–acceptor covalent organic frameworks and its impact on photocatalysis Abstract When new covalent organic frameworks (COFs) are designed, the main efforts are typically focused on selecting specific building blocks with certain geometries and properties to control the structure and function of the final COFs. The nature of the linkage (imine, boroxine, vinyl, etc.) between these building blocks naturally also defines their properties. However, be...
