Polymers with [2,2′-Biquinoline]-diyldimethanamine Units in the Main Chain and Their Metal–Polymer Complexes with Copper(I)

New monomers of the biquinoline series—diyldimethanamines—have been synthesized, and polymers having biquinoline units in the main chain and their metal–polymer complexes with cuprous chloride have been obtained using these monomers. The resulting starting compounds and polymers have been studied using NMR spectroscopy, HPLC, and simultaneous thermal (thermogravimetric and differential thermal) analysis, and the mechanical characteristics of the polymers and metal–polymer complexes have been examined. It has been shown that the structure and physicochemical properties of the polymers based on synthesized diyldimethanediamines largely depend on the position of groups in the biquinoline moiety and the presence of interchain coordination bonds in the polymer.
