摘要：

The mesogenic properties of copper octakisalkylthiophthalocyanine [(C6S)(8)PcCu] were studied by differential scanning calorimetry (DSC), Xray and optical microscopy. This phthalocyanine forms columnar hexagonal (Col(h)) mesophase. Thin films of (C6S)(8)PcCu were prepared by spin-coating technique. Thermally induced molecular reorganization within the films was studied by the methods of ellipsometry and UV-Vis absorption spectroscopy. Heat treatment produces molecular ordering which is believed to be due to stacking interaction between neighbouring phthalocyanine moieties. The differences in structural organization of the heated and unheated films were stated. These differences in structural organization in their turn are found to influence the electrical properties of the films. (c) 2007 Elsevier B.V. All rights reserved.
