New Amino Methyl Coumarin Derivative for OLED Blue Emitter |
| 초록 |
New blue emitting material, 7-phenylamino-bis(4-methyl-coumarin) (P-DMC) including coumarin moiety was synthesized by Ullman reaction.[1] Optical and electronic properties were examined by UV-Vis. absorption spectrum, PL spectrum, and cyclic voltammetry. UV-Vis. spectra of P-DMC in solution and film state showed maximum absorption wavelengths of 391 nm and 403 nm, respectively. PL spectra of P-DMC showed maximum emission wavelengths of 445 nm and 489 nm in solution and film state. Non-doped OLED device was fabricated by using the synthesized material as an emitting material. P-DMC compound exhibited efficient luminescence property. EL spectrum of P-DMC had a maximum value of 485 nm |
