摘要：

Optical properties of poly(2,5-dialkoxy-p-phenylenebutadiynylene) (PDAPB), such as optical absorption, photoluminescence (PL) and electroluminescence (EL), have been studied. The electronic energy structures of PDAPB have been determined by optical and electrochemical measurements. Strong PL with high quantum efficiency has been observed in PDAPB, therefore, PDAPB can be considered as a candidate for use in EL materials. Intense EL has been demonstrated in PDAPB for the first rimer in conducting polymers with two C-C triple bonds in a unit in the main chain. Anomalous temperature dependence in the absorption spectrum and PL have also been observed.
