DOI: 10.1002/macp.202500007
Abstract: Chirality induction in aprotic polar solvents is challenging due to disrupted intermolecular interactions and the high conformational flexibility of random‐coil polymers. Herein, a scalable strategy using chiral BINOL as the sole chiral source to induce… read more here.

DOI: 10.1021/acs.macromol.6b02688
Abstract: Polypeptides have inherent secondary structures, such as α-helix, β-sheet, and random coil structures, depending on their amino acid sequence. β-Cyclodextrins (CDs) as ligands of molecular recognition sites were introduced into poly(l-lysine) (PLL), which undergoes a… read more here.

DOI: 10.1038/s41428-019-0222-3
Abstract: The macromolecular structure of highly 1,6-glucose-branched β-1,3-glucan (6BG3) was elucidated spectroscopically by modification and complexation with chromophoric reporters. The circular dichroism spectra of 4-(dimethylamino)benzoic acid (DABz)-modified 6BG3 showed a relatively small but obvious bisignate couplet… read more here.
