To obtain a new compound of a sulfur atom-containing aromatic hydrocarbon compound, and useful as a constituent material of an organic electroluminescence element having high thermal stability, high luminescent characteristics and a low drive voltage.
This new compound is the one of formula I [An is a divalent group composed of a mono- to hexa-cyclic aromatic ring (substituted with one or more kinds of 1-30C alkyls and the like) or the like; Ar1 and Ar2 are each a single bond (with the proviso that the single bond is limited to one of Ar1 and Ar2, and in the case, the other is a sulfur atom-containing polyarylene comprising a heterocycle having two or more heterocycles), a 5-30C divalent group having sulfur atom, or the like; R1 to R4 are each a 6-20C aryl (substituted with one or more kinds of H, a 1-30C alkyl and the like), or the like], e.g. a compound of formula II. The compound of formula I is obtained by forming a compound of formula III (e.g. a compound of formula IV) into a Grignard reagent, and coupling the obtained Grignard reagent with a compound of the formula Br-An-Br (e.g. 9,10-dibromoanthracene).
