Abstract
The present application relates to a divalent platinum complex with a high color purity, which has a structure of chemical formula (I). The present application further provides an organic electroluminescent device, including a cathode, an anode, and an organic layer. The organic layer includes one or more of a hole injection layer, a hole transport layer, a light-emitting layer, a hole blocking layer, an electron transport layer, or an electron injection layer. At least one layer of the organic layer includes the compound of the structural formula (I).
Claims19
A divalent platinum complex, being a compound having a structure of formula (I):
- wherein,
- R1 to R23 are each independently selected from hydrogen, deuterium, halogen, amino, carbonyl, carboxyl, thioalkyl, cyano, sulfonyl, phosphino, a substituted or unsubstituted alkyl having 1 to 20 carbon atoms, a substituted or unsubstituted cycloalkyl having 3 to 20 ring carbon atoms, a substituted or unsubstituted alkenyl having 2 to 20 carbon atoms, a substituted or unsubstituted alkoxy having 1 to 20 carbon atoms, a substituted or unsubstituted aryl having 6 to 30 carbon atoms, or a substituted or unsubstituted heteroaryl having 3 to 30 carbon atoms, or any two adjacent substituents are linked or fused to form a ring;
- A1 to A4 are each independently selected from hydrogen, deuterium, halogen, amino, carbonyl, carboxyl, thioalkyl, cyano, sulfonyl, phosphino, a substituted or unsubstituted alkyl having 1 to 20 carbon atoms, a substituted or unsubstituted cycloalkyl having 3 to 20 ring carbon atoms, a substituted or unsubstituted alkenyl having 2 to 20 carbon atoms, a substituted or unsubstituted alkoxy having 1 to 20 carbon atoms, an aryl having 6 to 30 carbon atoms, or a substituted or unsubstituted heteroaryl having 3 to 30 carbon atoms, or any two adjacent substituents are linked or fused to form a ring;
- the heteroaryl containing a heteroatom including one or more of N, S, or O;
- and the “substituted” refers to substitution with halogen, deuterium, amino, cyano, or C1-C4 alkyl.
