The invention provides dianthracene compounds shown in a general formula I in the specification. In the general formula I, L1 and L2 independently represent single bonds, substituted or unsubstituted heterocyclic aromatic groups of C2-C60 or substituted or unsubstituted hydrocarbon aromatic groups of C6-C60; L3 represents a substituted or unsubstituted heterocyclic aromatic group of C2-C60 or a substituted or unsubstituted hydrocarbon aromatic group of C6-C60; R10, R11, R12, R13, R14, R15, R16, R17, R18, R21, R23, R24, R25, R26, R27 and R28 independently represent hydrogen, halogen and substituted or unsubstituted alkyl or alkoxy of C1-C10. The compounds have good luminescence properties, high electron transport capacities and terrific solubility and can be used in luminescent materials, electron transport materials and hole-blocking materials in the electroluminescence field. The invention also provides an organic electroluminescence device at least comprising a pair of electrodes and organic luminescent media between the electrodes. The organic luminescent media at least comprise the dianthracene compounds.

A series of bipolar anthracene derivatives containing hole-transporting triphenylamine and electron-transporting benzimidazole moieties were synthesized and characterized. These compounds possess high thermal properties and quantum yield in toluene solution but their photoluminescence spectra are sensitive to the polarity of the solvent. Three types of devices were fabricated to investigate their electron-transporting and hole-transporting as well as light-emitting properties. The electroluminescence spectra for the three derivatives B1, B3 and B4 show that they emit blue light, while the B2-based devices produced white light at a low current density because of the electromer formation. Moreover, a single layer OLED device for B4 exhibited a current efficiency of 3.33 cd A-1 with a pure blue color of CIE (x,y) of (0.16, 0.16) at 20 mA cm-2 and a maximum brightness of 8472 cd m-2 at 8.7 V.
