Synthesis and Characterization of Rare Earth Corrole-Phthalocyanine Heteroleptic Triple-Decker Complexes.

摘要: We recently reported the first example of a europium triple-decker tetrapyrrole with mixed corrole and phthalocyanine macrocycles have now extended synthetic method to prepare series rare earth corrole–phthalocyanine heteroleptic complexes, which are characterized by spectroscopic electrochemical methods. The examined complexes represented as M2[Pc(OC4H9)8]2[Cor(ClPh)3], where Pc = phthalocyanine, Cor corrole, M is Pr(III), Nd(III), Sm(III), Eu(III), Gd(III), or Tb(III). Y(III) derivative OC4H9 substituents was obtained in too low yield characterize, but for purpose comparison, Y2[Pc(OC5H11)8]2[Cor(ClPh)3] synthesized similar manner. molecular structure Eu2[Pc(OC4H9)8]2[Cor(ClPh)3] determined single-crystal X-ray diffraction showed be central macrocycle unit on each end. Each complex undergoes up eight reversible qua...
