Key Points

This research aims to understand the mechanism of photoredox activity in perylene diimide radical anions, focusing on their electron transfer capabilities.
Utilized perylene diimide radical anions as photocatalysts.
Investigated static quenching mechanisms during consecutive photoinduced electron transfer processes.
Analyzed the efficiency of aryl-halide reduction under various conditions.
Demonstrated significant static quenching of excited states of perylene diimide radical anions.

Implication

Investigates the photoredox role of perylene diimide radical anion in electron transfer, suggesting new photocatalytic pathways.

Abstract

The radical anions of perylene diimides (PDI •- * ) are increasingly used photocatalysts in consecutive photoinduced electron transfer (conPET) for aryl-halide reduction. Despite this, the mechanism behind this reduction by...
