Abstract
Homo- and hetero-dinuclear nickel(II), copper(II), and oxidovanadium(IV) complexes of a Schiff-base-fused phthalocyanine (pc) with bulky substituents, 2,6-dimethylphenoxy and t-butyl groups, were prepared and characterized. The introduced salen-like Schiff-base unit was shown to affect the spectral feature based on the pc unit in the near infrared region, the Q band being widely split over 600–800nm. A fairly large ferromagnetic interaction (J=6.0cm−1) was observed for the CuII(pc)–CuII(salen) homo-dinuclear complex, while an antiferromagnetic interaction (J=−3.2cm−1) was observed for the CuII(pc)–VIVO(salen) hetero-dinuclear complex.
