Article Description

Based on a D-π-A structural strategy incorporating carbazole as a mild electron-donor and sulfone as an electron-acceptor with a π-conjugation- breaking feature, two novel blue-violet emitting materials (CzS1 and CzS2) were successfully designed and synthesized. The two compounds exhibit high-efficiency fluorescent emissions of intramolecular charge-transfer transition type, with impressively high quantum yields in both solution and film states. CIE below 0.06 and excellent current/power efficiencies up to 1.89 cd A/1.58 lm W were achieved with their corresponding nondoped devices. These performances currently represent the best results for OLEDs with CIE < 0.06. Moreover, single-carrier devices were also fabricated to demonstrate the bipolar characteristics as well as to understand the different electroluminescence performance of the two fluorophores. © 2013 American Chemical Society.
