Cellulose oligomers were synthesized via cellodextrin phosphorylase-catalyzed reactions using α-D-glucose 1-phosphate monomers and D-glucose primers. The products prepared at relatively high primer concentrations self-assembled into highly grown nanoribbon network structures. The nanoribbons were composed of cellulose oligomers with degree-of-polymerization (DP) values of 8-9 with certain degrees of DP distribution and displayed the cellulose II allomorph. A formation mechanism for the unique nanostructures was proposed based on analyses of reaction time-dependent differences of the product solutions.
