Thermal Activation of Asymmetry Amplification Effects in Helical Polymer-Metal Complexes. [PDF]

Angew Chem Int Ed Engl
The formation of helical polymer‐metal complexes between chiral poly(phenylacetylene)s (PPAs) and metal ions can trigger different asymmetry amplification effects, e.g. screw‐sense enhancement, helix inversion, or the sergeants‐and‐soldiers effect. Adding a metal‐scavenger resin (nonreversible) or lowering the temperature (reversible) can reverse the ...

Consecutive Complex Aggregation Pathway in Covalent Helical Polymer-Metal Complexes: Nanospheres with Controlled P/M Macroscopic Chirality. [PDF]

Small
Helical polymer‐metal complex nanospheres following a consecutive aggregation pathway allow the creation of chiral polymeric particles capable of memorizing their macroscopic chirality and the properties associated with it, such as circularly polarized luminescence (CPL) emission. Abstract Kinetically trapped and thermodynamic nanospheres with opposite

Coaxial Helices in Chiral Supramolecular Aggregates from Highly Hindered Chiral Allenes. [PDF]

Angew Chem Int Ed Engl
Supramolecular helical aggregates describing two coaxial helices rotating in the same or opposite direction are obtained from the self‐assembly of chiral allenes. The internal helix is described by the allene stack, while the external one, a 4‐helix, is described by the four allene substituents.

Conformational Kinetics in Chiral Poly(diphenylacetylene)s: A Dynamic P/M Memory Effect

Angewandte Chemie, Volume 135, Issue 32, August 7, 2023., 2023
The combination between the conformational control of the pendant group in a chiral poly(diphenylacetylene) with the steric hindrance at the poly(diphenylacetylene) main chain results in the selective memorization of either P or M helical senses in the polymer.
