Claims16
A red phosphorescent compound having the following formula:
- wherein Ar1 is selected from substituted or non-substituted pyridine, substituted or non-substituted quinoline and substituted or non-substituted phenanthroline, and Ar2 is selected from substituted or non-substituted pyridine and substituted or non-substituted quinoline.
A red phosphorescent compound having the following formula:
- wherein Ar1 is selected from substituted or non-substituted pyridine, substituted or non-substituted quinoline and substituted or non-substituted phenanthroline, and Ar2 is selected from substituted or non-substituted pyridine and substituted or non-substituted quinoline.
An organic light emitting diode device, comprising:
- a first electrode;
- a second electrode facing the first electrode;
- and
- an emitting material layer between the first and second electrodes and including a red phosphorescent compound having the following formula:
- wherein Ar1 is selected from substituted or non-substituted pyridine, substituted or non-substituted quinoline and substituted or non-substituted phenanthroline, and Ar2 is selected from substituted or non-substituted pyridine and substituted or non-substituted quinoline.
