摘要：
Both the "D-A" and "two-in-one" strategies are simultaneously applied in designing deep-blue emitters. Two emitters show deep-blue emission with CIE coordinates of (0.15, 0.08) and (0.15, 0.06). Both of them exhibit excellent electro-luminescence performance, high singlet exciton yields (31%), and a small efficiency roll-off (external quantum efficiencies: less than 12% at 1000 cd m-2). © 2015 WILEY-VCH Verlag GmbH & Co.
