Abstract:
1. A novel soluble compound that is a distyrylarylene derivative represented by general formula (1) and has a solubility (20° C.) of 0.5% by weight or greater in an organic solvent, general formula (1) being: wherein Ar 1 , Ar 2 , Ar 4 and Ar 5 each independently represent a substituted or unsubstituted phenylene group, a substituted or unsubstituted naphthalene group, a substituted or unsubstituted anthracene group, a substituted or unsubstituted diphenylanthracene group, a substituted or unsubstituted phenanthrene group, a substituted or unsubstituted acenaphthene group, a substituted or unsubstituted biphenylene group, a substituted or unsubstituted fluorene group, a substituted or unsubstituted carbazolyl group, a substituted or unsubstituted thiophene group, a substituted or unsubstituted triazole group or a substituted or unsubstituted thiadiazole group; R Ar at least one substituent group selected from: a fluorendiyl group comprising a substituent group selected from: aryl groups having 6 to 30 carbon atoms, arylalkyl groups having 7 to 30 carbon atoms, heteroarylalkyl groups having at least one nitrogen atom, oxygen atom and sulfur atom and 2 to 30 carbon atoms, heterocyclic groups having 2 to 30 carbon atoms, alkanoyl groups having 1 to 20 carbon atoms; cycloalkanoyl groups having 6 to 30 carbon atoms, aryloyl groups having 6 to 30 carbon atoms, and heteroaryloxyl groups having at least one oxygen atom and sulfur atom and 2 to 30 carbon atoms, wherein the substituent is itself substituted with at least one group selected from aforesaid (a) to (i); and excluding a case where the fluorendiyl group is substituted with two benzene rings; R
