Fund Project: The authors gratefully thank Prof. Hui-Jun XU of the Institute of Photographic Chemistry, Academia Sinica, for providing the phthalocyanine samples,and Alexander von Humboldtstiftung for providing the LB machine.

Langmuir-Blodgett (LB) films of tetra-nonyl phthalocyanine copper (TNPcCu) were prepared.Molecular arrangement and orientation of these films were studied in detail.LB multilayer films of TNPcCu show a very Strong x-ray diffration peak and two weak peaks which indicate that the LB films form a quasi-crystal structure which molecules are arranged orderly.IR reflection absorption spectra and polarized VIS absorption spectra not only confirm the previous result but also indicate that phthalocyanine rings orient nearly perpendicular to the substrate surface and perpendicular to the lifting direction and the side-chain segments are not preferred oriented.
