<p>PURPOSE: A phenanthridine derivative compound is provided to obatin an organic light emitting diode with excellent light emitting property. CONSTITUTION: A phenanthridine derivative compound is denoted by chemical formula 1 or 2. An organic light emitting diode contains an anode, a cathode, and the phenanthridine derivative compounds inserted between the anode and cathode. The organic light emitting diode further contains a hole injection layer, a hole transport layer, an electron blocking layer, a hole blocking layer, an electron transport layer, or an electron injection layer formed by monomer deposition or solution process.</p> |
