Multigram synthesis of bis[(trimethylsilyl)ethynyl]benzenes suitable for post-polymerization modification

Abstract

Novel substituted bis[(trimethylsilyl)ethynyl]benzenes have been prepared as versatile building blocks for organic functional materials. The resulting effects of replacing sulfur by selenium and tellurium on photophysical and electrochemical properties have been examined. Polymerization via microwave-assisted Cu(I)-catalyzed azide–alkyne cycloaddition (CuAAC) and subsequent post-polymerization modification by oxidation reveals the utility of the developed building blocks.
