Paragraph 0199-0202; 0214-0216, (2021/03/03)
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.

Page/Page column 28, (2008/06/13)
The present invention is a light emitting device material characterized by containing an anthracene compound represented by the following general formula (1) or general formula (3), and the present invention allows a light emitting device having high luminous efficiency and excellent durability. (R 1 to R 10 are a hydrogen atom, alkyl group, cycloalkyl group, heterocyclic group or the like. At least one of the R 1 to R 10 is a substituent represented by the following general formula (2).) (R 11 to R 18 are a hydrogen atom, alkyl group and cycloalkyl group. X is an oxygen atom or sulfur atom, and Y is a single bond, arylene group or heteroarylene group. Any one of the R 11 to R 18 is used for linking with Y, and ± is used for linking with the anthracene skeleton.) (R 19 to R 37 are a hydrogen atom, alkyl group, cycloalkyl group, heterocyclic group or the like. n is 1 or 2. A is a heteroarylene group or arylene group. Any one of the R 19 to R 27 and any one of the R 28 to R 37 are used for linking with A.)
