Abstract
The present invention provides a phosphorescent compound of one of following formulas:
Claims18
A red phosphorescent compound having the following formula:
- wherein each of Ar1 and Ar2 is independently selected from hydrogen, a substituted or non-substituted heteroaromatic group, a substituted or non-substituted alicyclic group and a substituted or non-substituted aliphatic group, and at least one of Ar1 and Ar2 is not hydrogen.
A red phosphorescent compound having the following formula:
- wherein each of Ar1 and Ar2 is independently selected from hydrogen, a substituted or non-substituted heteroaromatic group, a substituted or non-substituted alicyclic group and a substituted or non-substituted aliphatic group, and at least one of Ar1 and Ar2 is not hydrogen.
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 each of Ar1 and Ar2 is independently selected from hydrogen, a substituted or non-substituted heteroaromatic group, a substituted or non-substituted alicyclic group and a substituted or non-substituted aliphatic group, and at least one of Ar1 and Ar2 is not hydrogen.
