<p>There are provided oligoarylene derivatives capable of emitting blue light at high luminous efficiency which are represented by the following general formulae (1) to (4): Ar<1> - Ch - Ar<2> Ch<1> - L - Ch<2> Ar<3> - (L<1>)a - Ch<3> - (L<2>)b - Ar<4> Ar<5> - Ch<4> - (Ar<7>)n - L<3> - (Ar<8>)m - Ch<5> - Ar<6> wherein Ch, Ch<1> and Ch<2> are respectively a group containing at least one substituted or unsubstituted condensed aromatic ring having 14 to 20 nuclear atoms; Ch<3>, Ch<4> and Ch<5> are respectively a substituted or unsubstituted arylene group having 14 to 20 nuclear atoms; Ar<1>, Ar<2>, Ar<3>, Ar<4>, Ar<5> and Ar<6> are respectively a substituted or unsubstituted aryl group having 5 to 30 nuclear atoms; Ar<7> and Ar<8> are respectively a substituted or unsubstituted arylene group having 5 to 30 nuclear atoms; L<1>, L<2> and L<3> are respectively a connecting group; and a, b, n and m are respectively an integer of 0 to 1, as well as organic electroluminescent devices using the same.</p> |
