Synthesis and Properties of d-π Conjugated Poly(phenylene silane)s

Abstract

Poly(phenylene silane)s were constructed by step-growth copolymerization between difunctional Grignard reagents and dichlorodimethylsilane in moderate yields. 1H NMR spectroscopy confirmed the structure of the desired copolymers. Gel permeation chromatography showed narrow molecular dispersibility and conceivable molecular weights. Based on thermogravimetric analysis and luminescence studies, the synthesized copolymers were found to act as potential emitters in organic light-emitting diode displays.
