Unsymmetric metallophthalocyanines (M=Zn, Co, Ni) carrying alkylthio and acetyl- oxyethylthio groups on peripheral positions were prepared from 4,5-bis-alkylthio-phthalonitrile, 4,5-bis-(acetyloxyethylthio)-phthalonitrile, and the corresponding anhydrous metal salts Zn(CH3COO)(2), NiCl2, and CoCl2. The extremely soluble compounds were characterized by their IR, H-1 NMR, and UV/Vis spectra. Their long wavelength absorption band was found to be bathochromically shifted; their solubility is superior to that of symmetrical phthalocyanines.
