α(β)-tetra-(methoxy-phenoxy)-zinc phthalocyanine are synthesized by employing 3(4)- nitrobenzene-1,2-dicarbonitrile as precursors. They are characterized by spectrum methods and elemental analysis. The UV-Vis spectrum, photoluminescence spectra of spin-coated film and solid pellet are compared. The electroluminescent devices are fabricated by using spin coating. The results indicate that the fluorescence of solid phthalocyanine has a red-shift of more than 145 nm compared to that in solution. The fluorescences are broader in solid state than that in solution. The fluorescence of β-substituted phthalcyanines has a more red-shift than α-substituted phthalcyanines. The electroluminescent spectra around 856 and 862 nm are consisted with the photoluminescence spectra of spin-coated film. The shorter inter-molecule space leads to the large red-shift of the fluorescence.
