Özet:In this study; ferrocenyl and naphthalenyl substituted quinoxaline derivatives; 5,8- bis (2,3- dihydrothieno [3,4-b] [1,4] dioxin-5-yl)-2- (naphthalen-2-yl)- 3- ferrocenyl- 4a,8a-dihydroquinoxaline; 5,8- bis (2,3-dihydrothieno [3,4-b] [1,4]dioxin-5-yl) -2- (phenyl) -3-ferrocenylquinoxaline; 5,8-bis (2,3-dihydrothieno [3,4-b] [1,4]dioxin-5-yl) -2,3- di(naphthalen-2-yl)quinoxaline and trihexylthiophene and thiophene coupled benzimidazole derivatives; 4-(tert-butyl)-4,7-bis(4-hexylthiophen-2-yl)spiro[benzo[d]imidazole-2,1-cyclohexane] and 4-(tert-butyl)-4, 7-bis(thiophenyl)spiro[benzo[d]imidazole-2,1-cyclohexane] were used as photosensitizers to broaden the active area of diaryliodonium salts. Both quinoxaline and benzimidazole derivatives are expected to be efficient in cationic photopolymerization with a variety of vinyl and oxide monomers at room temperature upon long wavelength UV irradiation. Photopolymerization will be initiated by diphenyliodonium salts and monitored with Optical Pyrometry. Characterization will be completed with optical absorption, flourescence studies and photopolymerization under solar irradiation.
