| 摘 要： | 近几年来，静电自组装成膜材料的合成、薄膜的制备、表征和功能研究已得到了迅速发展^1-6]，但对成膜材料分子结构与薄膜性质间构效关系的研究报道则较少^6]。杂多化合物具有特殊的结构特征和氧化还原性质，而半菁化合物是备受关注的二阶非线性光学和光电转换材料^7，8]，二者形成的静电自组装薄膜是一类在光、电和催化等众多领域中有着潜在应用前景的纳米材料^4]。本文报道了3种含磷钼酸根和不同结构的半菁阳离子的静电自组装膜，旨在探索不同阳离子对薄膜性质的影响。

| Abstract: | Three kinds of new electrostatic self-assembled muhilayer films were prepared with alternating ad-sorption of H3PMo12O40 and hemicyanine derivatives, and characterized with UV-visible absorption spectrosco-py and cyclic voltammetry. The results show that these films are vertically uniform and electrochemically active with surface-controlled behavior, and the charge transfer may occur between H3PMo12040 and hemicyanine de-rivatives in the films. The electron transfer rates of the three films are derived to be 0.0027, 0.0019 and 0.00066 s^-1, respectively, which decrease with increasing the thickness of the hemicyanine layers in the films. |
