Two D–A‐type molecules, 4‐N‐[4‐(9‐phenylcarbazole)]‐3,5‐bis(4‐diphenylamine)phenyl‐4H‐1,2,4‐triazole and 4,4′‐(9‐(4‐(1‐phenyl‐1H‐phenanthro[9,10‐d]imidazol‐2‐yl)phenyl)‐9H‐carbazole‐3,6‐diyl) bis‐(N,N‐diphenylaniline), are designed and synthesized. Organic lightemitting diodes based on them exhibit deep‐blue emission and the singlet formation ratios are higher than the simple spin‐statistics of 25%...
We applied the master equation method to investigate the anisotropic transport property of the 4,4′-bis((E)-2-(naphthalen-2-yl)vinyl)-1,1′-biphenyl molecular crystal based on first-principles calculation. It is found that the hole mobility has the largest value along the [100] direction, while electrons have the best transport property along the [010] direction. The anisotropic transport property...
