Abstract

Abstract:

Organic light-emitting diodes(OLEDs) have attracted great interest because of their potential applications in full-color flat-panel displays and solid-state lighting. Compared with great progress of organic red- and green-light-emitting materials and diodes, few blue-light-emitting materials and diodes with high performances have been reported. It is really difficult to realize organic deep-blue device with low operating voltage, high luminescent efficiency and good stability because of the relatively wider energy gap of blue-light-emitting materials. In general, white organic light-emitting diodes(WOLEDs) can be obtained by incorporating either three primary colors(red, green and blue) or two complementary colors(blue and yellow or orange). No matter which method, organic blue-light-emitting materials are necessary. In addition, blue light can generate other low-energy emission, such as green and red, by utilizing a color-change medium. So the realization of organic blue-emitting materials with high performances is critical for the development and application of OLEDs. In this paper, we clarified the recent progress of investigations on organic blue fluorescent materials and phosphorescent materials. The application of organic blue light-emitting materials in the blue and white organic light-emitting diodes was also introduced. Based on the present work, the investigation and application of organic blue light-emitting materials were finally prospected.

Key words: organic electroluminescence, blue-emitting materials, fluorescent and phosphorescent materials, high luminescent efficiency, good stability
