Outline of Final Research Achievements

Functional extension of lightweight and flexible organic materials is a promising approach toward a novel advanced material for various applications. We focus on metal complexes (MCs) as functional moieties, demonstrate fabrication of nano-fibrillar organic/inorganic-hybrid materials of MC and self-assembling molecular tool, and have aimed to enhance their functions via orientation of MCs induced by the self-assembling tool. Glutamide (G) derivatives obtained from a glutamic acid has been employed as a self-assembling molecular tool. We confirmed that the MC/G systems comprising MCs and G derivatives formed nano-sized fibrillar assembly in various solvents after temperature treatments as results of spectroscopies and microscopies. The results also indicated that the MC on MC/G systems aligned with chirality in various solutions. The effect of assembling on the functional properties like emission and catalytic abilities has been discussed for the nano-fibrillar materials.
