Controlled ROS generation in pyridinium-functionalized nanocatalysts for selective photooxidation

Abstract

A pyridinium-functionalized CP was ultrasonically transformed into nanoparticles, delivering a recyclable photocatalyst for selective alcohol oxidation. Notably, water addition triggers 1O2 generation via •O2− and H2O interactions, markedly boosting selectivity. This work presents the first exploration of pyridinium-bearing CPs functioning as nanocatalysts for controlled photooxidation.
