Organic light emitting diodes (OLEDs) are becoming the major solution of next generation lighting technologydue to their successful applications in solid-state lighting and full-color flat-panel displays. To the present, cyclometalated iridium (III) complexes are the most promising phosphorescent guest materials for highly efficient OLEDs because of their short excited lifetime (microsecond time-scale), color tuning flexibility, high quantum yields and thermal stability.The research is mainly aimed at the synthesis of phosphorescent moleculesand the understanding ofthe light-emitting mechanisms. The projects include:

1. Phosphorescent metal complexes: Ir, Pt, Re, Ru, Os, Au phosphorescent complexes with excellent photoluminescence and charge transporting properties

2. Thermally-activated delayed fluorescent materials: to design new TADF structureto improve triplet electron to singlet effective back-propagation for higher device efficiency;

3. Chiral materials: designed and synthesized chiral fluorescent, phosphorescent and thermally-activated delayed fluorescent materials with high asymmetric factor (g factor), for circularly polarized (CPL) emissionto manufacture3D display devices;

4. Supporting materials for OLEDs devices: the design and synthesis of electron transport materials, hole transport materials and host materials.
