| Abstract |
Recently, Non-doped white OLEDs have been attracting much attention due to the low-cost and easy fabrication process which offered offer great applications in display and lighting source. Doped emitting layer in conventional OLEDs have been reported in many literatures, but research on host-free systems is not much explored yet. In this study, star-shaped 3Py-DPAc and InDPAc-BT-CN were synthesized as blue emitter and red emitter, respectively, to realize non-doped white OLEDs. 3Py-DPAc showed good solubility and aggregation induced emission behavior which are favorable for non-doped solution-processed system. White OLED system has been driven by charge transfer and charge trapping mechanisms from blue to red emitter. Finally, 3Py-DPAc and InDPAc-BT-CN were blended to compose a single emitting layer in white OLED. As a non-doped system WOLED devices, it showed CIE coordinates of (0.32, 0.34) which is close to pure white. |
