Pyrene-based conjugated porous polymers as photocatalysts for oxidative cycloaddition of phenols

Key Points

• This research aims to explore the efficacy of pyrene-based conjugated porous polymers (CPPs) as photocatalysts in cycloaddition reactions.
• Synthesis of two pyrene-based conjugated porous polymers
• Conducting visible-light-activated photocatalysis
• Performing oxidative [4 + 2] and [3 + 2] cycloadditions with phenols and alkenes
• The pyrene-based CPPs successfully catalyze cycloadditions under visible light
• Chromanes and dihydrobenzofurans are synthesized through the reactions
• High selectivity for the target products is observed.
