Mechanistic studies of the Photo-decomposition of substituted Bis(trichloromethyl)-1,3,5-triazine Sensitized by Merocyanine Dye

摘要

The photochemistry of a merocyanine dye (1)/triazine (2)two-component system that could be used as a visible light radical generator inphotopolymerization formulations has been investigated.The electron stransfer from excited merocyanine to triazine to generate a reative photoinitiating radical was proposed based on fluorescence quenching experiments and a product analysis study.
