The influence of the porphyrin and phthalocyanine ligand nature onto the yield and selectivity in the one-step synthesis of heteroleptic triple-decker early lanthanide (porphyrinato)(phthalocyaninates) is investigated with 6 porphyrins, 4 phthalocyanines and 2 lanthanides as examples. It is found that the presence of electron-donating substituents in the phthalocyanine macrocycle allows efficient one-step formation of symmetrical triple-decker complexes of [Por]Ln[Pc]Ln[Por] type. In contrast, in the case of unsubstituted phthalocyanine only formation of double-decker complex was observed. The method was found to be limited for the preparation of complexes, containing porphyrins with unsubstituted meso-positions because of their degradation upon reaction course as well as porphyrins with bulky meso-substituents as a result of steric hindrances.
