More Information
Summary:The present invention has a high amorphous property and provides a high efficiency and long-lived organic electroluminescence device having the characteristic of bipolar and indolo[3,2,1-jk] carbazole derivatives for realizing the same. The indolo[3,2,1-jk] carbazole derivatives of the present invention substitutes at least one of substitutable carbon atom, which constructs a bezene ring for forming an indolo[3,2,1-jk] carbazole frame, for nitrogen atom and combines the indolo[3,2,1-jk] carbazole frame with an electron acceptor. In addition, the chemical formula is displayed. [chemical formula 1] X is the carbon atom or the nitrogen atom in the chemical formula 1. At least one of the X is the nitrogen atom. When the X is the nitrogen atom, R is not existed. When the X is the carbon atom, the R is hydrogen atom, substitutable alkyl radical, Alkoxy group, aryl, or hetero-aryl. L is the electron acceptor. m and n is at least one integer.
