摘要： 利用LB技术研究了带有4个长碳氢链的酞菁铜化合物(CuC12Pc)的单分子膜及它与十八胺(ODA)、二十酸(AA)的混合LB膜的聚集结构形态. 结果表明这种酞菁铜化合物在气液界面上可以形成比较稳定有序的双层Langmuir膜, 且可以转移质量较好的多层LB膜. 利用原子力显微镜(AFM)研究了酞菁铜分子的聚集体结构, 发现CuC12Pc/AA混合膜表现为网状的聚集结构, 而CuC12Pc/ODA混合膜形成长岛颗粒状聚集, 并结合UV-Vis吸收光谱讨论了酞菁铜分子形成不同聚集结构的原因.

Abstract: Monolayers and multilayers of copper tetrakis (12-alkyloxycarbonyl)phthalocyanine (CuC12Pc), CuC12Pc mixed with octadecylammonium (ODA) and CuC12Pc mixed with arachic acid (AA) were prepared by Langmuir-Blodgett (LB) technique and their configurations were also studied. The results showed that the compounds form uniform and stable bilayer Langmuir films. Meanwhile, the LB films could be formed very well. The morphology and structure of mixed LB films were observed using AFM, which demonstrated that the configuration of mixed film showed net-like aggregates in the mixture of CuC12Pc/AA, but long island-like aggregates in the mixture of CuC12Pc/ODA. UV-Vis absorption spectra also indicated the reason of different aggregations of the CuC12Pc molecule formed in mixed LB films.
