The photoinduced electron transfer acid generation of four kinds of intra-molecular conjugated charge transfer compounds incorporated with substituted bis(trichloromethyl)-2,4,6-triazine have been studied in this work. According to the fluorescence quenching and the fluorescence changing of mixed solution with irradiation time it was indicated that the photo-induced electron transfer between triazine as an electron acceptor and intra-molecular charge tranfer compounds as an electron donor have occurred in these systems. From the acidity measurement it can be seen clearly that the systems studied were changed dramatically under irradiation. And the acid-induced crosslinking reaction of phenol-aldehyde resin/hexamethaoxy methyl triazine has also been tested successfully. A probable mechanism was suggested preliminarily.
