Phenothiazine과 Quinone계 분자간 전하 이동형 색소의 합성 및 광 퇴색

Syntheses and Photofading of Intermolecular Charge-Transfer Complex Dyes of Phenothiazine and Quinonoid Compounds

The charge-transfer(CT) complexes derived from phenothiazine as donor and quinonoid compounds as accepters were evaluated as coloring matter. Light fastness of the intermolecular charge-transfer(CT) complex dyes as well as absorption wavelength is an important factor when the complexes are applied to coloring matters. The photofading mechanism of CT complex dyes of phenothiazine and accepters were examined. The addition of effective radical scavenger, antioxidant and photostabilizer gave a remarkable enhancement of the photostability of CT dyes.
