Abstract
Alkylstyryl carbazole group containing poly(methacrylate) (Cz-PMA) was prepared and blended with poly [2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylene vinylene] (MEH-PPV). The blends were characterized by UV-Vis, photoluminescence (PL), and electroluminescence (EL) studies. The polymer blends showed two isolated PL emission peaks at 440 and 560 nm corresponding to their component polymers, but the only one EL emission peak of the MEH-PPV/Cz-PMA blended light-emitting diode (LED) appeared near 580 nm which corresponds to that of MEH-PPV. This result indicates that the energy of excited Cz-PMA was transferred into MEH-PPV, resulting in the enhancement of EL intensity.
