Two hole transport materials, N-([1,1'-biphenyl]-4-yl)-9,9-dimethyl-N-(4-(naphtho[2,1-b]benzofuran-6-yl)phenyl)-9H-fluoren-2-amine (DFA) and N-(9,9-dimethyl-9H-fluoren-2-yl)-9,9-dimethyl-7-(naphtho[2,1-b]benzofuran-6-yl)-N-phenyl-9H-fluoren-2-amine (TFA) were designed, synthesized and fully characterized. The photophysical and thermal properties of these two compounds were investigated by UV–vis absorption spectra, photoluminescence spectra, thermogravimetric analysis (TGA) and differential scanning calorimetry analysis (DSC), which indicated that DFA and TFA would be efficient hole transport materials due to their proper HOMO energy levels and excellent thermal stability. Then, green OLEDs with DFA and TFA as hole transport layer, respectively, were fabricated, NPB-based OLEDs was also prepared for comparison. It turned out that DFA- and TFA-based devices exhibited higher efficiencies than that of NPB-based device, and TFA-based device showed the best performances with current efficiency, power efficiency and external quantum efficiency of 41.68 cd/A, 32.04 lm/W and 12.04%, respectively.
