C6和C9位取代基对菲并咪唑衍生物光电性质的影响
Influence of C6-and C9-substituents on Photoelectric Properties of Phenanthroimidazole Derivatives
摘要
Abstract
To explore the influence of substituent at C6 and C9 positions of phenanthroimidazole,three hot exciton blue emitters TPAPPI-Py,TPAPPI-mPy and TPAPPI-Qu were synthesized.Based on TPAPPI-Py,TPAPPI-mPy and TPAPPI-Qu as the emitting layers in OLEDs,the EQEmax of the devices are 4.80％,5.25％and 3.29％with CEmax of 5.46,5.05,3.75 cd·A-1,respectively.Those results indicated that the weak electron-withdrawing substituents at the C6 and C9 positions did not affect the emission wavelength,but was beneficial for enhancing carrier transport capability.The efficiency roll-off of the device remains below 10％in the luminance range from 1-1 000 cd·m-2,in-dicating their excellent electroluminescence.关键词
