Two pyridine-containing triphenylbenzene derivatives of 1, 3, 5-tri (m-pyrid-3-yl-phenyl)
benzene (TpPyPB) and 1, 3, 5-tri (p-pyrid-3-yl-phenyl) benzene (TpPyPB)(see figure) with …

A record high efficiency and reduced efficiency roll-off were achieved for blue
phosphorescent OLEDs with novel bipolar host materials containing both carbazole electron …

The development of a new method for the assembly of unsymmetrical carbazoles is
reported. The strategy involves the selective intramolecular functionalization of an arene CH …
