Abstract
Organic light-emitting devices have drawn a great deal of interests and are successively under intensive study due to their high electroluminescence (EL) efficiency all over the visible region. There are several advantages of the OLED displays over traditional LCD or LED displays. First, OLED based displays could be much thinner than the LCD panel, and are as responsive as the CRTs, people won’t see any smearing from slow pixel response time that usually take place in LCD panels. In addition, OLEDs are also superior to LCD panels in terms of viewing angle. Second, an LED emits light from a seam between two layers of different materials, which is fine for small points of light but not for large displays. OLEDs emit light through the layers, so many can be fabricated next to each other for large displays. Nevertheless, there still exits some serious problems in application of OLEDs.
In this thesis, we will demonstrate you some intriguing photophysical properties of the novel materials that have the potentials in the application of OLEDs. Base on these photophysical properties found, we conclude some guidelines for the design of new generation of the OLED materials (metal complex based OLEDs). Including the ligand orientation effects, ligand charge-transfer effects, and steric hindrance effects.
