摘要：
In this paper we report on poly(paraphenylene) and its derivatives as active layers in light-emitting Schottky-like devices. The bandgap and therefore the colour of the electroluminescence emission is chemically tuneable over a wide spectral range. Electroluminescence spectra of poly(paraphenylene) and a soluble poly(paraphenylene) type ladderpolymer are presented. The possibility of tailoring the bandgap is demonstrated by examples of the phenylene ladderpolymer and alkyl-substituted polyphenylene copolymers. The absorption spectra and photoluminescence emission spectra of those polymers are presented.
