Abstract:
A novel synthetic approach towards heteroleptic triple‐decker crown‐phthalocyaninato complexes [(15C5) 4 Pc]M[(15C5) 4 Pc]M(Pc) and (Pc)M[(15C5) 4 Pc]M(Pc) [where (15C5) 4 Pc 2– = 2,3,9,10,16,17,24,25‐tetrakis(15‐crown‐5)phthalocyaninato dianion; Pc 2– = phthalocyaninato dianion; M = Sm, Tb, Dy, Tm and Y] has been developed. It utilises the application of diphthalocyaninatolanthanum, La(Pc) 2 , as a new source of the phthalocyaninato dianion instead of well known Li 2 (Pc). In contrast to the highly hygroscopic Li 2 (Pc), La(Pc) 2 is quite air‐stable and its use allowed a significant decrease in reaction times. All the synthesised complexes were characterised by UV/Vis and 1 H NMR spectroscopy as well as MALDI TOF mass spectrometry. The X‐ray structure of heteroleptic triple‐decker crown‐phthalocyaninato (Pc)Sm[(15C5) 4 Pc]Sm(Pc) was determined. These new heteroleptic phthalocyaninato complexes are interesting because of their potential as components in new supramolecular materials. (© Wiley‐VCH Verlag GmbH & Co.
