| 제목 | Synthesis and Characterization of HTL Derivatives of Phenothiazine Using Aromatic Moiety |
| 초록 | We report the synthesis and electroluminescent properties of new aromatic compounds as hole-transporting materials based on phenothiazine, such as 1,4-diphenothiazyl-benzene [DPtzB], 1,4-diphenothiazyl-xylene [DPtzX] and 9,10- diphenothiazyl-anthracene [DPtzA]. DPtzB thin film exhibited photoluminescence (PL) maximum emission peak and emission shoulder at 450 and 475 nm, and maximum emission at 447nm without emission shoulder was found in DPtzX thin film. When DPtzA was excited by incident light of 359 nm, DPtzA showed strong PL emission at 417nm and weak emission at 600 nm. Luminance efficiencies of DPtzB, DPtzX and DPtzA-based electroluminescence (EL) devices were 3.57, 3.46 and 0.47 cd=A, and power efficiencies of DPtzB, DPtzX and DPtzA-based EL devices were 48, 1.26 and 0.20 lm=W. |
