Development of Highly-Efficient Blue Host Materials : Synthesis, Thermal, Photophysical, Electrochemical, and Electroluminescent Properties |
| 초록 |
Three primary colors, i.e., blue, green, and red emitting materials, are essential for full-color OLED displays. Green and red light emitting materials have been already achieved with high brightness and efficiency. However, as yet, enhanced example of deep blue light emitting materials fully meets requirements for commercially feasible light emitting diodes. A challenging goal in this area is to achieve blue light emitting materials with long-term stability, high efficiency, operational lifetime, brightness, and color purity. Here in, high efficiency fluorescence blue devices were demonstrated based on new type of host materials. The EL performances are showing high efficiency(10.12 cd/A), long lifetime and low turn on voltage with a Commission Internationale d’Eclairage (CIEx,y) coordinates of x=0.13, y=0.17. |
