Abstract :Four metallo insert ignore into journalissuearticles values(zinc, copper, vanadyl, and indium); phthalocyanine derivatives bearing four aliphatic insert ignore into journalissuearticles values(hexylthio); groups were prepared from corresponding phthalonitrile compounds. The metallophthalocyanines were characterized with ultraviolet–visible spectroscopy insert ignore into journalissuearticles values(UV-Vis);, proton nuclear magnetic resonance insert ignore into journalissuearticles values(1H NMR);, Fourier transform-infrared spectroscopy insert ignore into journalissuearticles values(FT-IR);, and mass and elemental analyses techniques. Aggregation properties of metallophthalocyanines in solution were studied in varied concentration ranges. Thin films of metallophthalocyanines were obtained by spin coating technique. Optical measurements showed that transmittance values of metallophthalocyanine thin films obviously changed with respect to the metal ion in the phthalocyanines. Transmittance spectra of the phthalocyanines synthesized using different metal ions showed a variation of about 8% and 15% in transmittance spectra of the Q band region was obtained by mixing the two metal phthalocyanine insert ignore into journalissuearticles values(indium and zinc); solutions.
