Block Copolymers with Bipyridine Containing Segments: Synthesis and Self-Organization by Cu(I) Complexation

Eisenbach, Claus D.; Göldel, Andreas; Terskan-Reinold, Monika; Schubert, Ulrich S.

Abstract:

The synthesis and properties of segmented ABA triblock and (AB), multiblock copolymer systems with 6,6‘-disubstituted 2,2’-bipyridine (bpy) building blocks B and poly(oxytetramethylene) soft segments A are described. The access to the disubstituted bipyridines in large scale quantities was achieved by modification of conventional synthetic routes. In the presence of copper(1) ions these polymers formed mononuclear [C~(I)(bpy)c~om] plexes in solution through self-assembly. The complexed copolymers were microphase separated systems in bulk with nano to mesoscopic superstructures consisting of copper-bpy complex aggregates in a polyether matrix. The thermal, mechanical and elastomer properties of the block copolymers varied with composition.
