Synthesis, electrochemical and optical properties of stable yellow fluorescent fluoranthenes.
A novel series of thermally stable yellow light emitting fluoranthenes with an amine donor and a nitrile acceptor was prepared from a ketene-S,S-acetal under mild conditions without using an organometal catalyst. The organic light emitting device of yellow fluoranthene 10b exhibited substantially low turn-on voltage (2.6 V) and maximum brightness of 470 Cd/m(2) with luminance efficiency of 2.0 Cd/A without using any dopant.
