Silicon Analogues of Polyfluorene as Materials for Organic Electronics

Abstract

Poly(dibenzosilole)s have been increasingly reported as an alternative to polyfluorene in organic electronic materials. Poly(dibenzosilole)s show similar optical properties to polyfluorene, but with improved resistance to oxidation and thermal stability. Several poly(dibenzosilole)s and their co-polymers have been incorporated into organic electronic devices, such as light emitting diodes and solar cells. These materials have shown improved performance over their polyfluorene-based counterparts.
