Claims11
A compound, comprising a structure of Formula (I):
- wherein A1 is a pyridyl group, A2 is a phenyl group or a pyridyl group, and hydrogens of the A1 are both unsubstituted or substituted by a structure of Formula (i), Formula (ii) or Formula (iii), and at least one of hydrogens of the A2 is substituted by the structure of Formula (i), Formula (ii) or Formula (iii):
- wherein n is independently an integer of 0 to 4, R is independently a monovalent group having 1 to 60 carbon atoms, X is —NR14—, —S— or —CR15R16—, and R14, R15 and R16 are independently —H, an alkyl group or an aryl group.
An emitting layer of an organic light emitting diode (OLED), comprising a dopant comprising a structure of Formula (I):
- wherein A1 is a pyridyl group, A2 is a phenyl group or a pyridyl group, and hydrogens of the A1 are both unsubstituted or substituted by a structure of Formula (i), Formula (ii) or Formula (iii), and at least one of hydrogens of the A2 is substituted by the structure of Formula (i), Formula (ii) or Formula (iii):
- wherein n is independently an integer of 0 to 4, R is independently a monovalent group having 1 to 60 carbon atoms, X is —NR14—, —S— or —CR15R16—, and R14, R15 and R16 are independently —H, an alkyl group or an aryl group.
