A NEW RED-LIGHT SENSITIVE SYSTEM FOR THE PROCESS OF PHOTO-CROSSLINKING

doi:10.7517/j.issn.1674-0475.2002.03.169

Abstract

Abstract: The absorption and fluorescence spectra of Oxonol in different solvents were studied in this work.An abnormal solvatochromic phenomenon was observed.The photo-induced acid generation and photo fading effect of system composed of Oxonol and bis(trichloromethyl)triazine were studied.It was found that the system can initiate some prepolymers to crosslink under irradiation of red light effectively.In addition,the fluorescence emission and the fluorescence quantum yield of Oxonol in micellar system were also studied.The phenomenon observed was discussed preliminarily.

Key words: photoinduced electron transfer, photocrosslinking, photo-acid-generation, Oxonol dye, triazine compounds
