两个双（乙撑二氧噻吩）萘单体1，4-双（2-（3，4-乙撑二氧噻吩））-萘（M1）和2，6-双合成了2-（3，4-乙撑二氧噻吩）-萘（M2），（1，4-双（2-（3，4-亚乙基二氧噻吩））-萘）（P1）和聚电化学合成了2，6-二（2-（3，4-乙撑二氧噻吩））萘（P2），并对其进行了表征。通过循环伏安法、紫外-可见光谱和扫描电子显微镜对所得聚合物进行了表征。单体M2的氧化电位比M1的氧化电位低，共轭长度分别比M1和P1长。光谱电化学分析表明，这两种聚合物薄膜具有良好的电致变色性能，并表现出多重电致变色行为。此外，相应的P1/聚（3，4-乙撑二氧噻吩）（PEDOT）和P2/PEDOT器件具有良好的光学对比度（ΔT%）、快速的响应时间和优异的循环伏安稳定性。两种EDOT-萘-EDOT型聚合物的电致变色性能取决于取代位置。
Two bis(ethylenedioxythiophene)naphthalene monomers 1,4-bis(2-(3,4-ethylenedioxythiophene))-naphthalene (M1) and 2,6-bis(2-(3,4-ethylenedioxythiophene))-naphthalene (M2) were synthesized, and corresponding polymer poly(1,4-bis(2-(3,4-ethylenedioxythiophene))-naphthalene) (P1) and poly(2,6-bis(2-(3,4-ethylenedioxythiophene))-naphthalene) (P2) were electrochemically synthesized and characterized. Characterizations of the resulting polymers were performed by cyclic voltammetry, UV–vis spectroscopy and scanning electron microscopy. The oxidation potential of monomer M2 was lower than that of the M1, and the conjugation lengths of both the M2 and P2 were longer than the corresponding M1 and P1, respectively. Spectroelectrochemical analysis revealed that both the polymer films had good electrochromic properties and exhibited multi-electrochromic behaviors. Besides, the corresponding devices P1/Poly(3,4-ethylenedioxythiophene) (PEDOT) device and P2/PEDOT device showed satisfactory optical contrast (ΔT%), fast response time and excellent cyclic voltammetry stability. The electrochromic properties of two EDOT-naphthalene-EDOT style polymers are dependent on the position of substitution.
