报道了一种新的蒽端基聚对苯亚乙炔的合成与发光特性,分别考察了聚合物 P2的紫外吸收,荧光发射和电致发光光谱。结果表明,在聚对苯亚乙炔主链末端引 入蒽基团可改变其有效共轭长长及发光颜色,合成的模型小分子可证明这一点。电 致发光器件ITO/P2/Al在600 nm处发红光。

The synthesis and luminescent properties of a new, solution- processable conjugated polymer (P2) which was end-capped by anthracene were reported. The absorption, emission and electroluminescence (EL) spectra have been investigated respectively. The results indicated that the end-capped group of anthracene can obviously influence the energy band gap of the corresponding polymer (P1). The results were further confirmed by spectroscopic comparison with the model compounds. EL in the red region of the spectrum with a maximum at 600 nm was observed from the polymer film sandwiched between indium-tin-oxide and Al electrodes.

Key words: ANTHRACENE, ELECTROLUMINESCENCE, CHARACTERISTICS OF LUMINESCENCE
