New Blue Emitting Materials for Lighting |
| 초록 |
Organic light-emitting diodes (OLEDs) have attracted attention due to their possible applications. Such as lighting, we were synthesized new compound. New blue emitting materials based on naphthyl anthracene were synthesized by suzuki coupling reaction etc. These compounds were characterized by 1H-NMR, FT-IR and Mass. The obtained blue emitting materials has good thermal stability. The blue emitting materials film state showed maximum emission at 446 nm and 447 nm respectively. This were used as blue dopant material device displayed turn-on at 4.5 V and confirmed the maximum luminous efficiency from 1.38 lm/W (2.59 cd/A at 5.9 V) and 1.37 lm/W (2.56 cd/A at 5.8 V). EL spectra showed maximum luminous wavelength at 456 nm and exhibited CIE coordinate from (0.15,0.14). |
