The present invention relates to a dibenzo[c,g]triphenylene derivative, a material for an organic EL device comprising the same, a light emitting material for an organic EL device, a light emitting organic solution, an organic EL device in which an organic compound layer comprising a single layer or plural layers including at least a light emitting layer is interposed between a pair of electrodes, wherein at least one layer in the organic compound layer described above contains at least one kind of the dibenzo[c,g]triphenylene derivative described above and an equipment comprising the same. The present invention provides a novel compound which is useful as a constitutional component for an organic EL device, and a practical organic EL device which is excellent in a color purity and reduced in an operating voltage and which has a small leaked electric current is materialized by using the above compound.

A simple and efficient synthesis and crystallographic analysis of the partially fluorinated 7:8,9:10-dibenzo-1,2,3,4-tetrafluorotriphenylene, 1, in 59% yield is reported. Compound 1 is a blue luminescent [5]helicene in both solution and the solid state. It spontaneously forms enantiomorphous single crystals from racemic samples and exhibits slipped, face-to-face F···Cπ contacts within the stacks of
