| Abstract |
Two novel hole transporting materials namely, HTM 1A and HTM 1B were synthesized with significant yields. Both the materials were exhibited stable thermal decomposition temperature at 5 % weight reduction. The HOMO energy level of both materials were lying between -5.54 to -5.33 eV, which were matching with the adjacent layers in red phosphorescence OLEDs. Both of the materials were showed absorption below 385 nm and there was no absorption in the visible region. HTM 1B was showed better current and power efficiencies of 16.16 cd/A and 11.17 lm/W, respectively. The external quantum efficiency of HTM 1B was 13.64% which is better than NPB based similar reference device. |
