摘要:
An organic light emitting device is provided. The device has an anode, a cathode, and an emissive layer disposed between the anode and the cathode. The emissive layer further includes a molecule of Formula I (shown below) wherein an alkyl substituent at position R′5 results in high efficiency and operational stability in the organic light emitting device.
