In this review, we describe the recent advances in supramolecular helical assemblies
formed from chiral and achiral small molecules, oligomers (foldamers), and helical and …

Helical structures such as right-handed double helix for DNA and left-handed α-helix for
proteins in biological systems are inherently chiral. Importantly, chirality at the nanoscopic …

The helix reversal is a structural motif found in helical polymers in the solid state, but whose
existence is elusive in solution. Herein, we have shown how the photochemical …

The remarkable consequences in elongation, dynamic character, response to external
stimuli (eg, solvent effects, metal cations), and aggregation observed in helical poly …

The secondary structure of a dissymmetric and chiral poly (diphenylacetylene)(PDPA) is
elucidated by combining the data from NMR experiments (regioregular head to tail …

Herein, macromolecular gears composed of helical poly (phenylacetylenes)(PPAs) bearing
short oligopeptides as pendant groups are described, in which the two structural motifs …

Self-assembled helical polymers hold great promise as new functional materials, where
helical handedness controls useful properties such as circularly polarized light emission or …

Helix inversion in chiral dynamic helical polymers is usually achieved by conformational
changes at the pendant groups induced through external stimuli. Herein, a different …

A novel approach to the classical Sergeants and Soldiers effect, using chiral Sergeants and
chiral Soldiers, allows control over both helical and external chirality in helical polymers. In …

Poly (phenylacetylene) s bearing prim-and sec-amine groups are barely known because of
their poisoning activity toward the polymerization catalyst. Herein, we prepare 11 different …
