First claim
Opening claim text (preview).
What is claimed is: 1. A carrier generation material, having a chemical structure of: 2. An organic light-emitting diode, comprising: an anode; a cathode; a carrier generation material layer, including the carrier generation material as claimed in claim 1 , disposed between the anode and the cathode; a first light-emitting layer disposed between the anode and the carrier generation material layer; and a second light-emitting layer, disposed between the cathode and the carrier generation material layer. 3. A carrier generation material, having a chemical structure of: 4. An organic light-emitting diode, comprising: an anode; a cathode; a carrier generation material layer, including the carrier generation material as claimed in claim 3 , disposed between the anode and the cathode; a first light-emitting layer disposed between the anode and the carrier generation material layer; and a second light-emitting layer, disposed between the cathode and the carrier generation material layer.
