| Outline of Final Research Achievements |
The self-assembly of biomolecules into highly regular structures is essential in the construction of biological tissues and organs. Various biomolecular assemblies composed of nucleic acids, peptides, and lipids have been utilized as molecular building units for self-assembled materials. However, crystalline oligosaccharides have rarely been utilized in self-assembled materials. In this research, multidimensional self-assembled structures of alkylated cellulose oligomers were synthesized via in vitro enzymatic reactions. It was found that the alkyl chain length drastically affected the assembled morphologies and allomorphs of cellulose moieties. The modulation of the intermolecular interactions of cellulose oligomer derivatives by alkyl substituents was highly effective at controlling their assembly into multidimensional structures. This research proposed a new potential of crystalline oligosaccharides for structural components of unique molecular assemblies.
