To increase the fluorescence quantum yield of hybrid local and charge-transfer (HLCT) material, we introduce a symmetric linear D-pi-A-pi-D structure into molecular design and synthesized a new blue emitter, 2,2 '-(2 ',3 ',5 ',6 '-tetrafluoro-[1,1%4 ',1 ''-terpheny1]-4,4 ''-diyebis(1-(4-(tert-butyl)pheny1)-1H-phenanthro[9,10-d]imidazole) (4FBTPI). Organic light-emitting devices employing 4FBTPI as a dopant emitter show good performances, with CIE (Commission Internationale de l'Enclairage) coordinates of (0.15, 0.09), which is very close to NTSC blue light standard (0.14, 0.08), current efficiencies (CE) of 6.03 cd A(-1), external quantum efficiencies of 6.94%. This performance is comparable to those of recently reported state-of-the-art deep-blue materials with CIEy < 0.10. (C) 2017 Elsevier Ltd. All rights reserved.
