One class of blue thiophene electrochromic compounds include 3,4-(2,2-bis(2-oxo-3-phenylpropyl))propylenedioxythiophene, 3,4-(2,2-bis(2-oxo-3-phenylbutyl))propylenedioxythiophene, and 3,4-(2,2-bis(2-oxo-3-phenylamyl))propylenedioxythiophene. The thiophene electrochromic compounds can change color between blue and transparency. The thiophene compounds can be electropolymerized on the surface of the ITO glass to form a film. The film has characteristics of low driving voltage (within ±1V), fast response time, and large transmittance difference between colored-state and bleached-state (up to 77.5%). The thiophene electrochromic compounds can be used in the electrochromic window, rearview mirror, electrochomeric display, and the like.
一类蓝色噻吩电致变色化合物包括3,4-(2,2-双(2-氧代-3-苯基丙基))丙烯二氧噻吩,3,4-(2,2-双(2-氧代-3-苯基丁基))丙烯二氧噻吩,和3,4-(2,2-双(2-氧代-3-苯基戊基))丙烯二氧噻吩。这些噻吩电致变色化合物可以在蓝色和透明之间改变颜色。噻吩化合物可以在ITO玻璃表面电聚合形成薄膜。该薄膜具有低驱动电压(在±1V内)、快速响应时间和有色状态与漂白状态之间的大透射率差异(高达77.5%)的特点。这些噻吩电致变色化合物可以用于电致变色窗户、后视镜、电致变色显示器等。
