Abstract
The present invention provides a phosphorescent compound of following formula: wherein each of X1 and X2 is independently selected from substituted or non-substituted carboline, dibenzofuran, dibenzothiophene and fluorene.
Claims11
A phosphorescent compound of formula 1:
- wherein each of X1 and X2 is independently selected from substituted or non-substituted carboline, dibenzothiophene, fluorene and dibenzofuran, and at least one of X1 and X2 is selected from substituted or non-substituted carboline.
An organic light emitting diode device, comprising:
- a first electrode;
- a second electrode facing the first electrode;
- an emitting material layer between the first and second electrodes;
- a hole transporting layer between the first electrode and the emitting material layer;
- and
- an electron transporting layer between the second electrode and the emitting material layer,
- wherein at least one of the emitting material layer and the electron transporting layer includes a phosphorescent compound of formula 1, and each of X1 and X2 is independently selected from substituted or non-substituted carboline, dibenzothiophene, fluorine and dibenzofuran:
- and at least one of X1 and X2 is selected from substituted or non-substituted carboline.
