Abstract
Thiophene-containing triarylamine compounds are disclosed. The said compounds have a structure of triarylamine, and connect specific thiophene-containing group. The compounds may be used as hole transporting materials, hole injection materials, or the like in an electroluminescent device. Compared to existing hole transporting materials, hole injection materials, the novel compounds can also offer excellent device performance. An electroluminescent device and a formulation comprising the compounds are also disclosed.
