Research Abstract

This study aimed at construction of photo-responsive molecular recognition system using macrocyclic host molecules consisting of oligopyrrole and azobenzene units. Kinds of macrocyclic host molecules were synthesized and it was revealed that the photo-isomerization ratio of the macrocycles was highly depends on the substitution position as well as the kind of spacer between azobenzene and pyrrole units. These results open the way to the development of a new light-triggered supramolecular recognition system based on macrocylic host. We also developed the methodology for hierarchical organization of macrocyclic host molecule which was prepared through self-assembly of metal ions and organic ligands.
