Red-emitting material and organic electroluminescent device made by using the same

Abstract

A red emitting material consisting of porphyrin, wherein the fluorescence of porphyrin is utilized. Metalloporphyrin can also be used as the porphyrin. An organic electroluminescent element having a porphyrin containing light emitting. The porphyrin content in the light emitting layer may be 1.0% by weight or more. The light emitting layer functions as a hole injection and transport layer or an electron injection and transport layer. Alternatively, it may be possible to further provide a hole injection and transport layer or an electron injection and transport layer.
