New donor-acceptor (D-A) and donor-acceptor-donor (D-AD) systems with carbazole and benzophenone moieties as donor and acceptor, respectively, have been synthesized. Photolumi-nescence quantum yields of D-A and D-A-D molecules in thin film were 76 and 73%, respectively. Solution-processed organic light-emitting diodes containing these D-A and D-A-D molecules as emitters showed the maximum external quantum efficiencies of 6.9 and 10.4% with a peak wavelength of 520 and 521 nm, respectively.
