摘要：

Poly[o(m,p)-phenylenevinylene-alt-2,5-bis(trimethylsilyl)-p-phenylenevinylene], o(m,p)-PBTMS-PPV and related derivatives were prepared and their light-emitting properties were studied. The peaks of the photoluminescence spectra of p-PBTMS-PPV, o-PBTMS-PPV, and m-PBTMS-PPV were at 485, 470, and 440, respectively. New, fully conjugated polymers composed of both electron-transporting oxadiazole and hole-transporting carbazole moieties PPOX-CAR and PMOX-CAR were also prepared. The electroluminescence peaks of those polymers occurred at 495 and 450 nm, respectively. The maximum brightness of Al/PPOX-CAR/ITO single layer device was 500 cd/m(2) at 20 V.
