m-Terphenyl-modified carbazole host material for highly efficient blue and green PHOLEDS.
A simple m-terphenyl modified carbazole derivative, 9-phenyl-3,6-bis-[1,1';3'1'']terphenyl-5'-yl-9H-carbazole (CzTP) was developed. By using CzTP as a host material, the PHOLEDs showed the maximum power efficiencies (eta(p, max)) of 55 lm W(-1) for blue and 113 lm W(-1) for green, respectively.
