Webb[1] [2] In physical and analytical chemistry, infrared spectroscopy (IR spectroscopy) is a technique used to identify chemical compounds based on the way infrared radiation is absorbed by the compound. The absorptions in this range do not apply only to bonds in organic molecules. WebbWhile crystalline covalent organic frameworks (COFs) linked by C–C bonds are highly desired in synthetic chemistry, it remains a formidable challenge to synthesize. Efforts to generate C–C single bonds in COFs via de novo synthesis usually afford amorphous structures rather than crystalline phases.
