Electrochromic material and application

The invention relates to the field of organic light-emitting materials, in particular to an electrochromic material with a structural formula I: # imgabs0. In the oxidation-reduction process of the electrochromic material, an absorption spectrum is subjected to red shift from ultraviolet band absorption in a neutral state to infrared band absorption in an oxidation state, and the electrochromic material almost has no absorption peak in a visible light region. From the optical point of view, the polymer is an ion storage material with great potential, and a film made of the polymer is used as an ion storage layer and has huge commercial application potential in electrochromic devices. 本发明涉及有机发光材料领域，具体涉及一种电致变色材料，结构式如下式Ⅰ：#imgabs0#该电致变色材料在氧化还原过程中，吸收谱从中性态下的紫外波段吸收红移至氧化状态下的红外波段吸收，其在可见光区域内几乎没有吸收峰。从光学角度来看，该聚合物是极具潜力的离子存储材料，使用聚合物制成的薄膜作为离子存储层，在电致变色器件中的商用应用潜力巨大。
