Paper Abstract

A new three-component photoinitiator system consisting of a dye, an iron arene complex and a phenylglycine derivative was investigated by fluorescence quenching experiments and time resolved absorption spectroscopy. The efficiency of this three-component system in photopolymerization reactions is higher by a two-fold factor compared to that of the two- component system dye/arene complex or dye/amine derivative. The first step of the photoreaction occurs between the dye and the iron arene complex, the latter reacts through an electron transfer reaction either with the singlet excited dye or with the triplet excited dye according to the nature of the sensitizing dye. The proposed mechanism for the higher efficiency of the three-component system involved the absence of terminating radical formation.
