报道了聚（3，4-乙撑二氧噻吩）（PEDOT）的合成及性能。该聚合物显示出低带隙，比聚噻吩低0.5 eV。这导致非常显著的电致变色性质，因为掺杂的聚合物几乎是透明的，具有天蓝色色调，并且中性聚合物是蓝黑色的。低的能带-pp也导致通过电化学方法进行n掺杂的可能性。掺杂的聚合物的电导率高达200 S cm-1，和稳定性是显着的，远远优于我们在聚噻吩和聚吡咯家族的研究中观察到的。
The synthesis and properties of poly(3,4-ethylenedioxythiophene) (PEDOT) are reported. The polymer shows a low band-gap, 0.5 eV lower than that of polythiophene. This leads to very pronounced electrochromic properties since the doped polymer is almost transparent, with a sky-blue tint, and the neutral polymer is blue-black. The low band-pp also leads to the possibility of n-doping by electrochemical methods. The conductivity of the doped polymer is up to 200 S cm-1, and the stability is remarkable, much better than observed in our studies of the polythiophene and polypyrrole families.
