摘　　要：Benzoylfonnamide（BFA） derivatives are proposed as new photocagcd bases with good solubility in epoxy resin.Initially their structures were confirmed by ~1H NMR,^（13）C NMR,and elemental analysis.Next,we detail their thermal stability,solubility behavior,and photolysis products.Furthermore,the model photo-latent anion polymerization（AP） of epoxide system in the presence of BFA-dBA（N,N-dibenzyl-2-oxo-2-phenylacetamide） as a photocaged base has been investigated,and excellent photopolymerization profile is obtained.Benzoylfonnamide（BFA） derivatives are proposed as new photocagcd bases with good solubility in epoxy resin.Initially their structures were confirmed by ~1H NMR,^（13）C NMR,and elemental analysis.Next,we detail their thermal stability,solubility behavior,and photolysis products.Furthermore,the model photo-latent anion polymerization（AP） of epoxide system in the presence of BFA-dBA（N,N-dibenzyl-2-oxo-2-phenylacetamide） as a photocaged base has been investigated,and excellent photopolymerization profile is obtained.
