N2 - A PPV-based conjugated copolymer DIOXA-PPV containing electron-affinitive bis-1,3,4-oxadiazole and hole-transporting distyrylbenzene derivative was synthesized via Horner-Wadsworth-Emmons reaction. The HOMO, LUMO energy levels and band gap of DIOXA-PPV are determined to be -5.06, -2.98 and 2.08eV, respectively. The photoluminescence (PL) maxima show gradually transition from 515 to 544nm as the concentrations of DIOXA-PPV in C2H2Cl4 increase from 10-7 to 10-3M due to the formation of excimer. Single-layer light-emitting diode (LED) with a structure of ITO/DIOXA-PPV/Al emits bright yellow emission, the threshold voltage and maximum luminance are 4.6V and 188cd/m2, respectively. The EL emission maximum locates at 541nm, which is corresponding to the excimer emission.
