The Studies On The Luminescent And Photo-electronic Performances Of Cu(Ⅰ)-complex Phosphorescent Materials

Extensive attention has been paid for organic electroluminescence (OEL) for its unique advantages in the field of modern display technique. At the mean time, organic photovoltaic (OPV) devices become a research hotspot because the devices can be made with low cost, simple for techniques, and easy for large scale, it is anticipated to develop a new way for the application of solar energy or photo-detector.The purpose of this thesis is to develop the application of phosphorescent Cu(I) complex materials in OLED and OPV fields.1. Some derivatives of tetraazatriphenylene (PyPhen,Dicnq,DPPz and BDPz) can be synthesized readily by utilizing hydrothermal synthetic method. Comparing with traditional technique, the technique presents effective and simple processes, much high yields of products with higher purity can be harvested.2. Ten Cu(I) complexes were synthesized by using PPh3, DPEphos as the first ligands and four derivatives of tetraazatriphenylene, Bath as the second-ligands.3. Tuning color electrophosphorescent device based on [Cu(DPEphos)(Dicnq)]BF₄ was fabricated by the evaporating process in vacuum. A peak efficiency of 11.3 cd A-1 at a 16.2 cd m-2 and at a 0.14 mA cm-2 and a maximum luminance of 2322 cd m-2 at 12 V bias were achieved, respectively.4. Efficient white organic light-emitting diodes based on [Cu(DPEphos)- (Dicnq)]BF₄, in which the white emission composed of yellow emission from...
