Abstract
The composition described here comprises at least one hole-transporting compound, wherein the hole-transporting compound comprises a core covalently bonded to at least two arylamine groups, wherein the arylamine group optionally comprises one or more intractability groups. The composition can provide good film formation and stability when coated onto hole injection layers. Solution processing of hole transporting layers of OLEDs can be achieved with the composition described here. Good mobility can be achieved.
