Mechanistic studies of the photo-decomposition of substituted bis(trichloromethyl)-1,3,5-triazine sensitized by merocyanine dye
The photochemistry of a merocyanine dye (1)/triazine (2) two-component system that could be used as a visible light radical generator in photopolymerization formulations has been investigated. The electron transfer from excited merocyanine to triazine to generate a reactive photoinitiating radical was proposed based on fluorescence quenching experiments and a product analysis study.
