摘要：

Various spectral methods (IR absorption and reflectance-absorption, Raman scattering and UV-Vis absorption) were used for investigations of a family of copper phthalocyanines in non-polarized and polarized light. The spectra of bulk and thin film samples were compared and discussed: an orientation of selected copper phthalocyanines in Langmuir-Blogdett layers and interaction between the phthalocyanine dyes with solid substrates were studied and discussed. Molecular arrangement of the molecular skeleton on the solid substrates was also evaluated. The presence of dye aggregates in the Langmuir-Blodgett layers was shown confirming the data obtained in concentrated solutions and in Langmuir layers. (C) 2010 Elsevier B.V. All rights reserved.
