Bottom-Up Approach to Understand Chirality Transfer across Scales in Cellulose Assemblies

Giulio Fittolani et al.

Summary: This study presents a bottom-up approach to understand the transfer of chirality from single cellulose oligomers to supramolecular assemblies. It is found that cellulose oligomers self-assemble into bundles with controllable chirality, which is directly correlated to the stereochemistry of the oligomers. The chirality of the cellulose assemblies can be manipulated by altering the stereochemistry.

Oligocellulose from acid hydrolysis: A revisit

Feng Jiang et al.

Summary: The classical method of producing cellulose oligomers through hydrolysis of microcrystalline cellulose (MCC) in phosphoric acid has been re-examined. Hydrolysis products are fractionated to yield two types of cellulose oligomers with different average degrees of polymerization (DP). The cellulose oligomers with lower DP can be dissolved in both alkaline aqueous solutions and dimethyl sulfoxide, and exhibit type-II crystal structure. X-ray and neutron small angle scattering of the cellulose oligomers in solution show characteristics of rigid slabs.

Solvent-Assisted Fractionation of Oligomeric Cellulose and Reversible Transformation of Cellulose II and IV

Xin Zhang et al.

Summary: Oligomeric cellulose with a high degree of polymerization and purity was fractionated using solution processes, resulting in the presence of Cellulose IV2 crystals that can reversibly transform to II and back to IV using simple solvents.
