Synthesis of hetero-bi-functional dye having photochromism and electrochromism. Part 2: Optical properties and behaviors
چکیده انگلیسی

In the previous study, we synthesized and characterized the novel hetero-bi-functional chromic dye having spiroxazine moiety as a photochromic part and viologen moiety as an electrochromic part within the single dye molecular structure. This novel multi-functional chromic dye showed photochromic and electrochromic properties and DMSO solution. When UV irradiation and electric energy-on/off states were repeated, these photochromism and electrochromism properties were represented with a fairly good reversibility. First-order kinetics indicates that the open-to-close reaction of spiroxazine occurred more rapidly than the redox system reaction of viologen. Structural change of the spiroxazine to the merocyanine form was in difficulties due to the inclusion complex between dye and β-cyclodextrin, which displayed the dramatic decrease of absorption peaks.
