Benzothiophene derivatives of the general formula: (A)h-(X)k-(B)m-L-(C)n-(Y)p-(D)q (1). Further, there is provided an organic electroluminescence device comprising a negative electrode and a positive electrode and, interposed therebetween, organic thin-film layers of one or more layers including at least a light emitting layer, wherein at least one of the organic thin-film layers contains any of the above benzothiophene derivatives alone or as a component of mixture. Consequently, there are provided an organic electroluminescence device exhibiting high luminous efficiency and realizing blue light emission of prolonged life and novel benzothiophene derivatives for realization of the same. |
