제목 Multi-Phenylated Carbazole emitters for OLED via Diels-Alder Reaction
초록 We synthesized multi-phenylated carbazole derivatives such as 3,6-Bis[(2,3,4,5-tetraphenyl)phenyl]-9-ethylcarbazole(BTPEC) and 3,6-Bis(7,10-diphenyl-fluoranthene)-9- ethlycarbazole(BDPEC), through Diels-Alder reaction. These products were identified by NMR, Fab-Mass analysis. Electro-optical properties of these materials were characterized by cyclic voltammetry and, UV-visible and photoluminescence spectra. The maximum absorbance of BTPEC appeared at 307 nm and BDPEC showed maximum absorbance of 307 nm and 388 nm. And two compounds also exhibited PL peaks at 389 nm and 483 nm. When we used these two materials as hole injection layer and hole transport layer in OLED device, the devices showed about 3 cd=A and 2 cd=A, respectively
