Key Points

  • The aim is to explore a new pyrrolyl enone photoinitiator for effective photobleaching and thick-film curing.
  • Investigated a novel N-alkyl-substituted pyrrolyl enone photoinitiator (C7-DPP-C7).
  • Analyzed the photoinitiation mechanism under visible light illumination.
  • Examined thick-film uniformity in photopolymerization processes.
  • The new photoinitiator demonstrated efficient photobleaching during curing processes.
  • Achieved uniform thickness in thick-film photopolymerization applications.
  • Mechanistic insights revealed the underlying efficiency of the photoinitiator.

Abstract

Cleavage-type visible-light photoinitiators capable of efficient photobleaching and uniform thick-film curing remain rarely explored. Herein, we report a novel N-alkyl-substituted pyrrolyl enone photoinitiator, C7-DPP-C7, and investigate its photoinitiation mechanism and...
