摘要：

The optical and electroluminescence properties of a light-emitting poly(arylene vinylene) derivative comprising triphenylamine as the arylene unit (TPA-PPV) are demonstrated. TPA-PPV is soluble in common organic solvents, and has a high photoluminescent (PL) quantum yield (Phi(PL) = 0.94 in benzene). A single-layer light-emitting diode Indium-tin-oxide/TPA-PPV/Al utilizing blue-green light-emitting TPA-PPV as the emissive layer is fabricated, and luminance in excess of 612 cd/m(2), turn-on voltages of 1.5 V, and high luminous efficiency (3.0 lm/w) are reported.
