Zinc copper and cobalt phthalocyanines were achieved by reaction of starting compound with Zn CH3COO 2 CuCl2 and CoCl2 metal salts. Basic spectroscopic methods such as nuclear magnetic resonance electronic absorption mass and infrared spectrometry were used in the structural characterization of the compounds. Absorption excitation and emission measurements of the fluorescence zinc phthalocyanine compound were also investigated in THF. Then structural energy and electronic properties for synthesized metallophthalocyanines were determined by quantum chemical calculations including the DFT method. The bandgap of HOMO and LUMO was determined to be chemically active. Global reactivity I A η s μ χ ω and nonlinear properties were studied. In addition molecular electrostatic potential MEP maps were drawn to identify potential reactive regions of metallophthalocyanine M-Pc compounds. Photovoltaic performances of phthalocyanine compounds for dye sensitive solar cells were investigated. The solar conversion efficiency of DSSC based on copper zinc and cobalt phthalocyanine compounds was and respectively. The compounds have good solubility and show nonlinear optical properties. Zinc .
