| 제목 | Synthesis and Hole-Transporting Properties of Ethyl-Carbazyl Derivatives |
| 초록 | Our research team synthesized a new HTL material by using ethyl-carbazole moiety. Even though carbazole which was used in synthesis is well-known for excellent hole mobility most studies have dealt with carbazole as an emitting material, but few studies have focused on HTL. Here in, we report the synthesis of the ethyl-carbazole derivatives as a new hole transporting materials. The synthesized material was N,N’-diethyl-3,3’-bicarbazyl (E-Cvz-2), 9,9'-diethyl-6-(9-ethyl-carbazol-3-yl)-3,3'-bicarbazole (E-Cvz-3), 6-(9,9'-diethyl-3,3'-bicarbazol-6-yl)-9,9'-diethyl-3,3'-bicarbazole(E-Cvz-4A) and 9-ethyl-6-(9-ethyl-3,9'-bicarbazol-6-yl)-3,9'-bicarbazole (E-Cvz-4B). The electro-optical properties of these materials were characterized with cyclic voltammetry (CV), and UV-visible and photoluminescence (PL) spectroscopy. Moreover, multilayered EL devices were fabricated using these materials as a hole-transporting layer(HTL). |
