제목 Synthesis and Photophysical Properties of Triazole-Spiropyran Derivatives Obtained by Click Chemistry
초록 Photochromic materials have been attracting a great deal of attention because of their potential application in sensors. Among the photochromic molecules, spiropyrans are a well-known class of organic compounds with the ability to change their chemical structure when exposed to light of an appropriate wavelength, and regain their original isomer when placed in the dark, or upon exposure to light of a different wavelength. After irradiation, spiropyran converts from closed form (SP) to open colored form, the so-called merocyanine (MC). Click chemistry refers to the 1, 3-dipolar cycloaddition of azide with alkyne in the presence of CuSO4.5H2O, sodium ascorbate in a 1:1 solvent ratio of THF and H2O. The present investigation mainly focuses on the design and synthesis of triazole with spiropyran at the end-group through click reaction. Herein, we wish to present mono-, di- and tri- triazole functionalized spiropyran compounds and discuss their photophysical properties.
