| Outline of Final Research Achievements |
Semi-artificial branched-polysaccharides, amylose-grafted curdlans, were synthesized utilizing enzymatic polymerization. Amylose side chains on AGC maintain the original helical structure and the molecular inclusion ability. Despite of introduction of bulky amylose chains, CUR main chain also retains the original helical structure and the co-helical complex formation ability with conductive polymers, CNT or polythiophene. Thank to the difference in their molecular recognition properties between beta-1,3-glucan and alfa-1,4-glucan, AGC forms heterogeneous supramolecular assemblies possessing well-defined hierarchical superstructure. On the bases of this dendritic superstructure of AGC, a self-organized “Janus-type FRET system” was successfully constructed by assembling PT-1 with AGC, and therein, fluorescence energy of PT-1 on amylose side chain transfers to PT-1 on CUR main chain.
