A fluorene-based derivative having a specific structure and an organic
electroluminescence device in which an organic thin film layer comprising
a single layer or plural layers including at least a light emitting layer
is sandwiched between a cathode and an anode, wherein at least one layer
of the organic thin film layers described above comprises the above
fluorene-based derivative having a specific structure in the form of a
single component or a mixed component. The organic electroluminescence
device has a high luminous efficiency, and the fluorene-based derivative
materializes the same.
