N2 - Two phenanthroline derivatives containing a hole transporting triphenylamine and an electron transporting 1,3,4-oxadiazole unit have been prepared with high yield. UVâ€"vis absorption and fluorescence measurement indicated they are high efficient light-emitting materials. The compounds are 6-(5-(4-N,Nâ€-diphenylaminophenyl)-1,3,4-oxadiazol-2- yl) quinoxalino[2,3-f] phenanthroline (9, κ max=635nm, 40% quantum yield), and 1-ethyl-2-(4-(5-(4-N,Nâ€-diphenylaminophenyl)-1, 3,4-oxadiazol-2-yl)phenyl)imidazo[4,5-f]phenanthroline (14, Iκ max=461nm, 78% quantum yield). Preliminary study on electroluminescence for the two fluorescent dyes prepared from vacuum evaporation resulted in blue and red light emitting organic light emitting diodes (OLED).
