<p><P>PROBLEM TO BE SOLVED: To provide a polymer compound which provides a long life light-emitting device when used as a light-emitting material for the light-emitting device. <P>SOLUTION: The polymer compound includes a repeating unit represented by formula (1), and has a number average molecular weight of 10<SP>3</SP>-10<SP>8</SP>in terms of polystyrene. In the formula (1), Ar<SB>1</SB>, Ar<SB>2</SB>, Ar<SB>3</SB>, Ar<SB>4</SB>, Ar<SB>5</SB>, Ar<SB>6</SB>, and Ar<SB>7</SB>represent each independently an arylene group or a divalent heterocyclic group, and E<SB>5</SB>and E<SB>6</SB>represent each independently an aryl group (A) or a univalent heterocyclic group (B). n represents 2, and l, m, n, o, and p represent 0. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
