Highly efficient pure organic near-ultraviolet (NUV) electro-fluorescent materials with high electron mobility and improved hole mobility

Abstract

In this work, OLEDs based on the D–π–A molecules exhibit bright near-ultraviolet (NUV) to blue emission. Remarkably, doping achieves more balanced mobilities. Ultimately, highly efficient NUV-doped OLEDs with a 14.5% EQE for 9-PCZCFTZ were achieved.
