Heteroleptic phthalocyaninato-[2,3,9,10,16,17,23,24-octakis(octyloxy)phthalocyaninato] rare earth(III) triple-deckers: Synthesis and spectroscopic characterization

The homo-dinuclear heteroleptic phthalocyaninato-[2,3,9,10,16,17,23,24-octakis(octyloxy)phthalocyaninato] rare earth(III) triple-decker complexes (Pc)M[Pc(OCH)]M[Pc(OCH)] (M = Pr, Nd, Sm, Eu, Tb, Dy, Y, Ho, Er, Tm) (1a-10a) and (Pc)M[Pc(OCH)]M(Pc) (M = Nd, Sm, Eu, Tb, Dy, Y, Ho, Er, Tm) (2b-10b) were obtained by condensation of bis(phthalocyaninato) rare earths M[Pc(OCH)] (M = Pr, Nd, Sm, Eu, Tb, Dy, Y, Ho, Er, Tm), Li(Pc) and M(acac)·nHO (M = Pr, Nd, Sm, Eu, Tb, Dy, Y, Ho, Er, Tm). These novel compounds were characterized by H NMR, mass, electronic absorption (UV-Vis), and IR spectroscopic methods
