Highly efficient exciplex systems incorporating a 1,3,5-triazine derivative (3N-T2T) as an electron acceptor and caibazole derivative (Tris-PCz) as an electron donor are developed. We employed a simple device structure composed of only Tris-PCz and 3N-T2T as charge-transporting and emitting materials. The combination of the hole and electron mobility of Tris-PCz and 3N-T2T, respectively, the barrier free hole injection from the ITO to the EML and high triplet energies renders the green exciplex device to realize an exceptionally low driving voltage of 3.4 V at 1000 cdm-2 and maximum EQE up to 10.8% (32.7 cdA-1, 38.4 lm W-1).
