Electrochromic monomer compound, polymer, material and preparation method and application thereof

The invention belongs to organic high-molecular compounds, and particularly relates to an electrochromic monomer compound, a polymer, a material and a preparation method and application thereof. According to the invention, an acridine derivative is taken as a central core, 3, 4-ethylenedioxythiophene (EDOT) is taken as a monomer of an electroactive polymerization unit, a three-branch material which is easy to form a net structure is provided, and a uniform and flat polymer film can be formed through electrochemical polymerization. The polymer film can realize reversible switching from yellow to transparency, the optical contrast is 32.4%, the optical contrast is not obviously attenuated after 30,000 cycles, the response time is 0.4 s and 0.42 s, and the polymer film is an electrochromic material with good application prospects. 本申请属于有机高分子化合物，具体涉及一种电致变色单体化合物、聚合物、材料及其制备方法与应用。本发明以吖啶衍生物作为中心核，3,4-乙烯二氧噻吩(EDOT)为电活性聚合单元的单体，提供了一种三支型易形成网状结构的材料，经电化学聚合能形成均匀平整的聚合物薄膜。该聚合物薄膜能够实现从黄色至透明的可逆切换，光学对比度为32.4％，经过30000次循环光学对比度没有明显衰减，
