Control of Geometric Structure and Catalytic Function of Platinum-Containing Polymers Linked with Bidentate Phosphine Ligands
Phosphine ligands are widely used for transition metal compounds that catalyze various reactions. The present paper reports the coupling polymerization of optically active bidentate phosphine ligands, PPh2–R–PPh2 (R: spacer containing amino acid moieties) with PtCl2L2 (L: 1,5-cyclooctadiene, benzonitrile). The selectivity of trans-/cis-geometries, formation of polymers (−[−PPh2–R–PPh2–PtCl2−]n−) vs cyclic compounds depending on polymerization conditions, as well as chiroptical properties and hydrosilylation catalysis of the polymers were studied.
期刊介绍：
Macromolecules publishes original, fundamental, and impactful research on all aspects of polymer science. Topics of interest include synthesis (e.g., controlled polymerizations, polymerization catalysis, post polymerization modification, new monomer structures and polymer architectures, and polymerization mechanisms/kinetics analysis); phase behavior, thermodynamics, dynamic, and ordering/disordering phenomena (e.g., self-assembly, gelation, crystallization, solution/melt/solid-state characteristics); structure and properties (e.g., mechanical and rheological properties, surface/interfacial characteristics, electronic and transport properties); new state of the art characterization (e.g., spectroscopy, scattering, microscopy, rheology), simulation (e.g., Monte Carlo, molecular dynamics, multi-scale/coarse-grained modeling), and theoretical methods. Renewable/sustainable polymers, polymer networks, responsive polymers, electro-, magneto- and opto-active macromolecules, inorganic polymers, charge-transporting polymers (ion-containing, semiconducting, and conducting), nanostructured polymers, and polymer composites are also of interest. Typical papers published in Macromolecules showcase important and innovative concepts, experimental methods/observations, and theoretical/computational approaches that demonstrate a fundamental advance in the understanding of polymers.
