摘要：
Two random copolymers of phenylene vinylene and pyridinylene vinylene, ED-co-PyV-PPV and EM-co-PyV-PPV, were synthesized according to the Gilch route. The polymers possess good solubility in common solvents, and high thermal stability with 5% weight loss temperature above 378A degrees C. The weight-average molecular weight (M (w)) and polydispersity index of ED-co-PyV-PPV and EM-co-PyV-PPV are 3.12 x 10(5) and 1.40, and 2.30 x 10(5) and 1.96, respectively. Single-layer polymer light-emitting diodes (PLEDs) with indium tin oxide (ITO)/poly(3,4-ethylenedioxythiophene) (PEDOT):poly(styrenesulfonate) (PSS)/polymer/Ca/Al configuration were fabricated. The turn-on voltages of the PLEDs based on ED-co-PyV-PPV and EM-co-PyV-PPV were approximately 4.0 V and 2.8 V, respectively. The ED-co-PyV-PPV PLED device exhibited the maximum luminance of ca. 4380 cd/m(2) with maximum electroluminescence (EL) efficiency of 6.35 cd/A.
