Bipyridine-Containing Optically Active π-Conjugated Polymers Derived from Amino Alcohols: Examination of the Higher-Order Structures, Chiral Recognition, and Metal Coordination Based on Quantum Mechanical and Molecular Dynamics Calculations.

Helical π-conjugated polymers are promising as optically active functional materials. The present paper reports the synthesis of novel bipyridine-containing π-conjugated polymers with optically active amino-alcohol-derived side chains, examination of their higher-order structures, chiral recognition, and metal coordination properties. The polymers adopt a folded helical conformation and aggregate in CHCl/MeOH depending on the solvent composition, as supported by density functional theory calculations and molecular dynamics simulations.

Sintering of Platinum-Containing Conjugated Polymers: Gas Adsorption and Catalysis of the Formed Pt-Carbon Composites.

Pt-containing - and -linked poly(phenyleneethynylene)s were synthesized by the dehydrochlorination coupling polymerization of PtCl(PBu) with - and -diethynylbenzenes. The formed polymers were sintered at 900 °C to obtain Pt-graphene hybrids, whose structures were examined by Raman scattering spectroscopy, X-ray photoelectron spectroscopy (XPS), and X-ray diffraction (XRD) measurements. Shapes─facets, terraces, and steps─with average diameters of 2.
