Chemistry of ethynylene-bridged porphyrinoids: Triphyrin (2.1.1), Porphycene, Porphyrin ( and further expanded families

Séminaire du Dr Hiroko Yamada (Nara Institute of Science and Technology, Ikoma)

Abstract :

Porphyrin is one of the representative aromatic compounds and has a planar molecular structure with four pyrrole units connected by four meso-carbons. We have focused on a dipyrrylethene unit, where two pyrrole units are connected by ethene bridge. By the presence of ethynylene-bridge, porphyrinoids have different properties from traditional porphyrins due to their flexibility, possible cis-trans isomerization, coordination ability of double bonds, and etc. We have studied synthesis, structure and properties of various ethynylene-bridged porphyrin families. This presentation will introduce the chemistry of triphyrin (2.1.1)1, porphycene2, porphyrin( and hexaphyrin(
