摘要：
The syntheses of new ball-type Co(II) phthalocyanines containing 4,4'-(9H-fluorene-9,9-diyl)diphenol substituents at non-peripheral (complex 6) and peripheral (complex 7) positions are presented. These complexes were characterized by UV-Vis. FT-IR, mass spectroscopy and electrochemical methods. Both complexes exhibit metal and ring based redox processes, typical of cobalt phthalocyanine complexes. For 6, the metal based reduction was observed at -0.46 V followed by a ring based reduction at -1.40 V. The metal oxidation for 6 was observed at +0.16 V and the ring based oxidation at +1.05 V. For 7, reductions are easier but the oxidations are more difficult. The metal based reduction for 7 was observed at -0.38 V followed by a ring based reduction at -1.03 V. The metal oxidation for 7 was observed at +0.20V and the ring based oxidation at +1.35 V. (C) 2010 Elsevier Ltd. All rights reserved.
