Abstract: An electrochromic polymer having formula (1), a method for fabricating the same, and a component comprising the same are disclosed. A device fabricated from the electrochromic polymer is capable of varying between purple and transparent and has advantages of easy fabrication, wide viewing angle, rich colors, high contrast, low driving voltage, and reduced response time. The device can realize storage without power consumption, and can be applied to the field of electrochromic display device.

Abstract: 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.
