Abstract

original image

A series of novel materials based on bi(9,9-diaryfluorene)s are the first examples of pure aromatic hydrocarbons as potential UV emitters in organic light-emitting devices (OLEDs). The Figure, photographed in a normal lighting environment, shows strong red, green, and blue emission from corresponding fluorescent dye solutions pumped by a UV OLED from this work, demonstrating strong UV emission from the UV OLED, and its pumping capability.
