摘要
近年来随着高新技术的迅猛发展，激光技术和光化学也随之大量应用到先进材料中，为适应这种发展需要，开发感可见光和近红外光的光敏反应体系已成为十分迫切的研究课题［１，２］．方酸类染料是一类重要的功能性染料，广泛地应用于静电复印、太阳能电池和光记录材料［３］...
Visible photoinitiation systems composed of squarylium cyanine dye
and iodonium salt were studied in this work. Such systems possess a good thermostability and
high photochemical activity. Upon irradiation, the electron transfer reaction occurs between
excited dye and iodonium, leading to photobleaching of squarylium cyanine dye and cleavage
of iodonium to generate active radical. The results obtained indicated that squarylium cyanine
dye and iodonium salt combination can serve as a suitable visible photoinitiation system for
photocrosslinking of acrylates.
