Abstract
A platinum complex having at least one carbene fragment, and an OLED using the same are described. The platinum complex contains a platinum cation, a zero-valent nitrogen-containing heterocyclic bidentate chelate, and a dianionic nitrogen-containing heterocyclic bidentate chelate. The zero-valent nitrogen-containing heterocyclic bidentate chelate has at least one carbene unit coordinating to platinum. The dianionic nitrogen-containing heterocyclic bidentate chelate has at least one electron-withdrawing substituent, and forms two N—Pt bonds, or one N—Pt bond and one C—Pt bond, with the central platinum cation.
