Dye molecule-containing polymeric photosensitizer as a high-performance photocatalyst for aerobic chemical conversion

Polymeric photocatalysts (PHEMA-Xant/Eosin Y) were synthesized, efficiently catalyzing α-oxidation of N -aryltetrahydroisoquinolines and methylation of quinoxalin-2(1 H )-ones (>98% yield) with excellent recyclability (10 cycles) and gram-scale applicability.
