hotoinduced coloration system consisting of fluorane dye(FR) and iodonium salt(DPIOB) was investigated. Upon irradiation, the excited fluorane dye and iodonium salt may undergo electron transfer reaction to form FR+· and IPh·2 radical pair, the latter rapidly decomposes to phenyl radical (Ph·) and iodobenze, and the color form of ring opening ester (FRPh) subsequently is formed by radical coupling between FR+· and Ph·. The structure of FRPh possesses good stability, and thus it demonstrates electron transfer reaction is one of effective pathway to improve the color stability of fluoranedye.
