We designed and synthesized tri-O-acetylcellulose with hydrophobic poly(benzyl L-glutamate) at the reducing end (CTA-b-PBLG) and tri-O-methylcellulose with hydrophilic cellobiosyl and oligo(amino acid) residues at the reducing end via Huisgen 1,3-dipolar cycloaddition to elucidate those self-assembly structures. Hydrophobic CTA-b-PBLG showed micro phase separation in a thin film and in bulk after annealing over glass transition temperature of CTA segment. In contrast, amphiphilic end-functionalized tri-O-methylcellulose derivatives exhibited lower critical solution temperature at approx. 25�C in aqueous media, resulting in the formation of thermo-reversible hydrogel. Those structure-functions relationships will be discussed in our presentation.
