  Synthesis and Properties of Porphyrin-linked Indolizine

  摘要：

  The synthesis of porphyrin-linked indolizine has been achieved for the first time in a simple process from the reaction between a 5-formylindolizine (8) and dipyrrolomethane (10) giving the desired 1,7-bisindolidinoporphyrin (12). The electronic effect of the heterocyclic nuclei (12) is prominently observed in the Soret band of the UV-VIS spectrum. Temperature-dependence H-1 NMR analysis of 12 suggests the existence of an association of 12 causing restricted rotation around the bond between indolizine and porphyrin.
