Synthesis and Electro-Optical Properties of Diazocine Derivatives Substituted with Naphthyl Group in Different Positions |
| 초록 |
The new diazocine derivatives, 1-DAN and 2-DAN have been successfully synthesized and characterized. 1-DAN and 2-DAN, are different the positions of naphthyl substituted in the anthracene. In the film state, 1-DAN and 2-DAN exhibited absorption in the range of 354 to 402 nm and showed blue photoluminescence (PL) emission at 441 and 450 nm. The PL wavelength of 1-DAN was blue-shifted by 9 nm than that of 2-DAC. This is because the conjugation length is decreased by H atom-H atom repulsion between 1-naphthyl and anthracene. Organic light emitting diode (OLED) device using 2-DAN as emitting layer (EML) showed current efficiency of 1.76 cd/A. |
