【摘要】 <正>聚噻吩及其衍生物具有很好的环境热稳定性,易于制备,掺杂后呈现很高的电导性,所以作为一类重要的共轭聚合物有其更为广泛的用途。我们以聚（噻吩-3-乙酸）（P₃TEA）为聚阴离子,部分掺杂的聚苯胺（PANI）为聚阳离子,构筑具有全共轭结构的多层自组装膜。研究自组装膜的紫外吸收、电化学性能和光电性能。更多还原

【Abstract】 Full conjugated multilayer films from partially doped polyaniline（PANI） as polycation and carboxylated polythiophenes（P₃TEA） as polyanion are fabricated with the layer-by-layer（LBL） self-assembled（SA） technique.The experiment results reveal that the UV-Vis absorbance of PANI/P₃TEA LBL self-assembled films increase linearly with the increase of dipping cycle number which indicates that the amount of polyelectrolyte deposition on the surface of the films in every cycle is uniform.In conventional three-electrode CV test, the electrochemical properties of the LBL films increase with bilayer number and scan rates. Moreover,the optoelectronic conversion was also studied by assembling PANI/P₃TEA multilayer films on ITO substrates.Under illumination,the LBL SA films on ITO showed an effective photoinduced charge transfer because of their conjugated structure and the ITO current density changed with the number ofbilayers.更多还原
