Diarylethene이 첨가된 저융점 유-무기 하이브리드 유리의 광변색 특성

Diarylethene in photochromic materials was doped in organic-inorganic hybrid low-melting glasses were synthesized through a non-aqueous acid-base reaction process, which consists of network units including a small number of bridging oxides. The organic phase is a dichlorodimethylsilane while the inorganic phase is a tin(Ⅱ) chloride. Diarylethene was incorporated into the glasses without any degradation of its functionality. The open form of diarylenthene, which is converted from the opening one upon UV-irradiation, is change to the closed form visible light-irradiation. The rate constant of the photochemical reaction is 31.78 × 10?³s?¹ with 400 W UV lamp irradiation.
