摘要:

Radical generation from photoinitiation systems containing carbonylbiscoumarin dye with a radical-generating reagent, 3,3′-carbonylbis[7-(diethylamino)-2H-l-benzopyran-2-one](KCD-DA), with 2,2′-bis(2-chlorophenyl)-4,4′,5,5′-tetraphenyl-1,1′- bi- 1H- imidazole (BI) in a poly(methyl methacrylate) (PMMA) film have been investigated by laser flash photolysis using a total reflection cell.
