Rapid metal-free synthesis of pyridyl-functionalized conjugated microporous polymers for visible-light-driven water splitting

A rapid metal-free synthetic approach was applied to synthesize pyridyl-functionalized conjugated microporous polymers (PCMPs) via an aminative cyclization between aryl aldehydes and ketones without any metal catalysts. PCMPs exhibited suitable electronic structures for visible-light-driven water splitting, offering numerous opportunities in developing new polymer photocatalysts for future solar-to-chemical conversion.
