Synthesis, Separation and Characterization of Unsymmetrically Substituted Phthalocyanines

Unsymmetrically substituted (phthalocyaninato)nickel(II) complexes –7 were synthesized by statistical condensation of 4,5‐dipentoxy‐ ( 2a ), 4,5‐diheptyl‐ ( 2b ), 3,6‐dihexoxy‐ ( 2c ), and 3,6‐diheptylphthalonitrile ( 2d ) with 3,4,5,6‐tetraphenylphthalonitrile ( 1 ) and separated by column chromatography. The obtained phthalocyanines 3–7 were characterized by UV‐, IR‐, and 1 H‐NMR spectroscopy.
