Abstract

Abstract : Mechanochemical Suzuki polycondensation offers a sustainable alternative to classical solvent based approaches, affording high yields and short reaction times. Abstract : The mechanochemical Suzuki polycondensation constitutes a sustainable alternative to classical solvent-based polymerization reactions for poly(phenylene)s. In order to establish a basic understanding of the process, important reaction parameters like the milling material, halide type and polymerization system are investigated. Under optimized conditions, we have been able to synthesize linear polymers with an outstanding degree of polymerization of 164, in a ligand free environment – in as little as 30 minutes. In addition, the developed principle is broadened to a hyperbranched system with high temperature resistance and high yields in short reaction times.
