- Dianthracene compound containing pyridyl at tail end and application thereof
-
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.
