"Chemistry of ethynylene-bridged porphyrinoids: Triphyrin (2.1.1), Porphycene, Porphyrin (2.1.2.1) and further expanded families" Monday November18th 2019

Hiroko YAMADA (Hyamada @ ms.naist.jp)

Nara Institute of Science and Technology, Ikoma, Japan

 Visite du professeur Hiroko YAMADA du NAIST


Nous avons monté un accord d’échanges etudiants de chimie avec NAIST, partenaire japonais particulièrement dynamique.
Cette année, comme l’an passé, un étudiant de master rejoindra pour son stage une des equipes du NAIST. L’an dernier Florence LIM Master 1 de chimie. a rejoint l’équipe du professeur  Gwenael RAPENNE et cette année le Professeur  Hiroko YAMADA sera l’hôte de Leo GAILLARD Master 1 de chimie.

Abstract:

Porphyrinis one of the representative aromatic compounds and has a planarmolecular 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-transisomerization, coordination ability of double bonds, and etc. We have studied synthesis, structure and properties of various ethynylene-bridged porphyr in families. This presentation will introduce the chemistry of triphyrin (2.1.1)1, porphycene2, porphyrin(2.1.2.1)3 and hexaphyrin(2.1.2.1.2.1)4.
