Abstract
Unsymmetrical metal-free phthalocyanine was synthesized through cyclotetramerization of 4-[2,6-dimethyl-4-(4-tert-butyl-phenylazo)phenoxy]phthalonitrile and 4-(hexylthio)phthalonitrile in the presence of lithium in [Formula: see text]-pentanol, then metal-free phthalocyanine was obtained by acidification with acetic acid. Finally, metalation was achieved by refluxing metal-free phthalocyanine in [Formula: see text]-pentanol in the presence of zinc (II) salt. The structure of synthesized phthalocyanine derivatives were characterized by using proton nuclear magnetic resonance, mass spectrometry, ultraviolet–visible spectroscopy, and Fourier transform infrared spectroscopy. The HOMO–LUMO energies were computed using density functional theory. The HOMO–LUMO energy difference is 2.28 eV. The calculated results were consistent with the experimental data. In addition, aggregation behaviors and general trends for photophysical properties of these phthalocyanine derivatives were studied in tetrahydrofuran. The emission intensities of these phthalocyanine derivatives were strongly quenched by 1,4-benzoquinone in tetrahydrofuran.

Abstract
Thin films of metal phthalocyanines (M: Co, Zn, Ni) substituted with four 3,5-bis(2[Formula: see text],3[Formula: see text],4[Formula: see text],5[Formula: see text],6[Formula: see text]-pentafluorobenzyloxy)benzyloxy groups have been prepared by the spin-coating technique. Optical properties and surface morphology of the thin films of metallophthalocyanines have been investigated as a function of organic solvents of acetone, chloroform, tetrahydrofuran, dimethylformamide and dimethylsulfoxide. Results show that optical properties and surface morphology of the prepared films depend on the type of organic solvent used.
