摘要
通过交替吸附H4SiW1 2 O40 和双偶极半菁衍生物制备了一个新颖的无机 -有机杂化自组装多层膜 .紫外可见光谱和X射线衍射研究证实了半菁衍生物 /H4SiW1 2 O40 多层膜可被均匀沉积厚达至少 12层 ,具有平均膜厚 5 3nm (半菁阳离子层加SiW1 2 O4-40 层 )的二维有序结构 ,膜中半菁衍生物与H4SiW1 2 O40 间发生了较强的电荷转移作用 .循环伏安研究表明 。
A new self-assembled multilayer film is prepared by alternating adsorption of H4SiW12O40 and a hemicyanine derivative. UV-vis spectroscopy and X-ray diffraction analysis demonstrate that the film is uniformly deposited up to at least 12 layers with mean film thickness being 5.3 nm per layer (the hemicyanine cation layer and SiW12O404- layer), and that the charge transfer occurs between H4SiW12O40 and the hemicyanine derivative in the film. Cyclic voltammetry shows that this novel inorganic-organic composite film is of good electrochemical activity.
