Synthesis and Characteristic of Diazocine Derivatives Substituted with Carbazole in m, p-positions |
| 초록 |
M-DAC and P-DAC have been successfully synthesized and characterized. The ultraviolet-visible (UV-Vis) absorption of M-DAC and P-DAC showed in the range of 373nm to 394nm and exhibited maximum photoluminescence (PL) emissions at 466 and 481 nm in the film state. PL wavelength of P-DAC is red-shifted by 15 nm than that of M-DAC.Thisis because carbazole is substituted for para position and the conjugation length is increased. M-DAC and P-DAC OLED devices exhibited current efficiency of 3.09 and 2.80 cd/A and C.I.E(x,y) values of (0.17, 0.27) and (0.18,0.33). |
