Outline of Final Research Achievements

In this research organogelator candidates which consist of the ferrocene unit have been prepared. It has been suggested that two amino acid residues in the structure are necessary to form a stable organogel. Addition of an oxidizing agent such as NaClO induces the collapse of the gel, and reproduction of the gel was observed by addition of a reducing agent such as glutathione. It has been found out that the on-off switching of gel formation can be achieved by red-ox reaction. Two kinds of glutamaic acid-based coumarin derivatives show a quite different trend against gelation in organic solvents in terms of inter- or intramolecular hydrogen bonds involved. It has been found out that addition of the valinate structure into the coumarine derivative could improve its gelation ability.
