Product Name:2-[4-(9,10-Di(naphthalen-2-yl)anthracen-2-yl)phenyl]-1-phenyl-1H-benzimidazole

English Name:2-[4-(9,10-Di(naphthalen-2-yl)anthracen-2-yl)phenyl]-1-phenyl-1H-benzimidazole

CAS No.:561064-11-7

Aliases:2-(4-(9,10-Di(naphthalen-2-yl)anthracen-2-yl)phenyl)-1-phenyl-1H-benzo[d]imidazole, 1-Phenyl-2-[4-(9,10-di-2-naphthalenylanthracen-2-yl)phenyl]-1H-benzimidazole

Molecular Formula:C53H34N2

Physical Properties:Pale yellow to yellowish-green crystalline powder. Insoluble in water; soluble in dichloromethane, chloroform, toluene and other organic solvents. Melting point is above 280°C with decomposition; it exhibits high thermal decomposition temperature and good glass-transition temperature, and can form uniform films by vacuum evaporation. It shows blue fluorescence in both solution and thin-film states.

Uses:Mainly used as an organic light-emitting diode (OLED) material, especially for blue-emitting layers or bipolar host materials. The benzimidazole moiety provides good electron-transporting ability, while the anthracene/naphthalene skeleton offers excellent thermal stability and blue emission performance. It is also investigated as a charge-transporting layer or interface-modification material in organic photovoltaics and perovskite devices.
