摘要：

Charge drift mobilities of five oxadiazole derivatives doped in polycarbonate (PC) were evaluated with the time-of-flight technique. It is demonstrated that oxadiazoles incline to having electron-transport characteristics. In particular, an oxadiazole with naphthyl substituent (BND) was found to possess high potential of electron transport; the electron drift mobility of 50 wt % BND doped PC was 2.2×10-5cm2 V-1 s-1 at an electric field of 7.5×105 V cm-1 at room temperature. In addition, incorporating strong electron-releasing substituents into oxadiazoles was demonstrated to add hole transport characteristics to oxadiazoles.© 1995 American Institute of Physics.
