Study of metal cation selectivity by alkyl chain length between 1,2,3- triazole and spiropyran = Study of metal cation selectivity by alkyl chain length between 1,2,3- triazole and spiropyran

다국어 초록 (Multilingual Abstract)

Spiropyran (SP) is an important class of photochromic molecule. Under UV light irradiation, the closed form of SP can be converted into the open merocyanine (MC) form through spiro cleavage and the MC form can retain to their original SP form under visible light irradiation. In this study, we design and synthesize triazole linked spiropyran compounds by click reaction. In this opportunity, we present the synthesis of two metal binding site SP and 1,2,3-triazole linked through different length of alkyl chain. The reversible interconversion between the SP and MC form can attain by metal cations without any external stimuli. According to this phenomenon, SP is able to utilize as metal cations sensor. We find that different alkyl chain length between SP and 1,2,3-triazole can effect on selectivity of our metal sensor system.
