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.

Key words: Copper phthalocyanine compound, LB technique, AFM, Aggregate
