Conformational variability of helix sense reversals in poly(methyl isocyanate)

Hierarchical Approach to Flow Calculations for Polymeric Liquid Crystals

“…The rapid convergence to a stable conformation very similar to that obtained in Refs. [25][26][27][28] using the PCFF force field in the absence of solvent, and also very close to experimentally determined structures 29 . References [30][31][32] suggests that rigid helical conformations are indeed a robust characteristic of PPIC chains.…”

Chirality of photopolymerized organized supramolecular polydiacetylene films

“…It has been reported that polyisocyanate can form a stiff helical backbone due to competition between electronic and steric factors and the polyisocyanate can show chirality although the monomer is achiral. 10 This suggests that a similar case occurred in PDA films, although we cannot exactly verify this at the present stage.…”

“…These findings are similar to the case of polyisocyanate. 10 In the ex situ polymerized Cu(II)-PDA LB films, however, the sign of the CD signals was always the same. This suggested that a certain helical structure was predominantly formed in the LB films on a quartz substrate.…”

Synthetic Control of Helical Polyisocyanates by Living Anionic Polymerization toward Peptide Mimicry

“…Polyisocyanates with dynamic helicity − have been utilized to find the universal effects of chiral amplification on artificial helical polymers. ,, Practical routes to covalent chiral induction use chiral monomers/initiators/terminators. Optically active polyisocyanates from chiral monomers were first proven by Goodman and Chen , and more deeply explored by Green, − Okamoto, ,− Zentel, − and Lee − (Figure a).…”
