Abstract: α(β)-tetra-phenoxy phthalocyaninato zinc complexes have been synthesized via a two-step process using 3(4)-nitrobenzene-1,2-dicarbonitrile and phenol as precursors. The products were characterized by means of IR spectrum, UV-Vis spectrum, 1H NMR spectrum, mass spectrum and elemental analysis. The UV-Vis spectra, photoluminescence spectra of spin-coated film and pressed solid pellet were compared. The fluorescences of both compressed and spin-coated samples had red-shifts larger than 161 nm compared to that obtained from solution. In addition, their fluorescence peaks are broader than that in solution. The fluorescence of β-substituted phthalocyanines has a greater red-shift than that of α-substituted phthalocyanines. The two kinds of fabricated devices showed similar electroluminescent spectra around 880 nm.
