近年来,由于激光技术和光固化新技术的迅速发展,吸收光谱位于可见光区的光敏引发体系发展迅速.其中离子对内电子转移型染料光敏引发体系倍受重视.这一方面由于染料品种丰富,各种染料的吸收光谱范围几乎可覆盖整个可见光和近红外光区,因而用作光敏组分,有广范的选择余地,另一方面,由于阴、阳离子通过库伦力相互吸引,使光敏组分和引发组分预先组合,提高了二者的反应几率,同时克服了双分子能量或电子转移中反应速度受分子 In recent years, due to the rapid development of new laser technology and light-curing technology, the photoinitiation initiation system with absorption spectrum in the visible region has developed rapidly, and the photo-induced initiation system of the ion-pair electron transfer dye has drawn much attention because of the variety of dyes The absorption spectrum of the dye covers almost the entire visible and near-infrared region, and therefore has a wide range of options as a photosensitive component. On the other hand, since the positive and negative ions attract each other through Coulomb force, the photosensitive component Lead to pre-combination of components to improve the probability of both the reaction at the same time overcome the bimolecular energy or electron transfer reaction speed by molecules
