Novel Thieno[3,2-c]Pyridine Based Ir Complexes for Solution/Evaporation Hybrid OLED

Abstract:

A series of novel thieno [3,2-c] pyridine based phosphorescent Ir complexes have been successfully synthesized and characterized. The HTL-free devices were fabricated on ITO with a multilayered structure of ITO/PEDOT:PSS(45 nm)/host (TCTA or NPB):dopant (10~15 nm)/TmPyPb/LiF/Al by solution/evaporation hybrid process and showed relatively high efficacies. The high efficacy enables these emitters to serve as promising candidates in fabricating high quality RGB displays. The monochromatic large-area of 40 x 32 mm² OLEDs had also been demonstrated.
