MOLECULAR DEPOSITION FILM OF PORPHYRIN AND PHTHALOCYANINE BEARING OPPOSITELY CHARGED SUBSTITUENTS

Several kinds of porphyrin/porphyrin, phthalocyanine/phthalocyanine, p orphyrin/phthalocyanine self-assembled multilayer films-molecular depo sition (MD) films have been prepared by alternately dip-coating a subs trate into solution of oppositely charged chromophores. Alternate film growth was monitored by UV-Vis spectroscopy. The results strongly sug gest the formation character of layer-by-layer assembly of homogeneous films. The structures of the MD films have been characterized by quar tz crystal microbalance (QCM) and polarized UV-Vis spectroscopy. It is shown that the macroring of the porphyrin and/or phthalocyanine in th e MD films is orientated with an angle of 38 degrees and 32 degrees wi th respect to the normal of the substrate respectively.
