Abstract: A series of triazine derivatives (1a—1e) were synthesized in moderate yields as photoacid generators. All novel compounds synthesized were characterized with ¹H NMR and MS, and these data were found in good agreement with expected structures. Quantum yields of decomposition and acid formation of compound 1e in acetonitrile in different concentrations were measured when exposed at 405 and 365 nm. It was found that Quantum yields are strongly dependent on the wavelengths of light, rather than on their concentrations in acetonitrile. Decomposition and acid formation in acetonitrile of PAG 1e are more efficient at 405 nm than at 365 nm.

Key words: photoacid generator, triazine derivative, quantum yield
