Abstract
Treatment of dilithium phthalocyaninate [Li 2(Pc)] with Ln III(acac)(TPP) (Ln=Sm, Eu, Gd; acac=acetylacetonate; TPP=5,10,15,20-tetraphenylporphyrinate) prepared in situ from Ln(acac) 3· nH 2O and (TPP)H 2 in 1,2,4-trichlorobenzene led to the formation of heteroleptic triple-decker complexes (TPP)Ln III(Pc)Ln III(TPP) and (Pc)Ln III(Pc)Ln III(TPP) along with a small amount of the double-decker complexes Ln III(Pc)(TPP). The new compounds were characterised with 1H NMR, UV–Vis, near-IR and Fourier transform ion cyclotron resonance (FTICR) mass spectrometry.
