HIGH-MOLECULAR COMPOUNDS AND POLYMERER LIGHT EMITTING DEVICES MADE BY USING THE SAME

摘要

High-molecular compounds comprising repeating units represented by the general formula (1) or (2) and having number-average molecular weights of 10<3> to 10<8> in terms of polystyrene: (1) [wherein Ar<1> and Ar<2> are each independently a trivalent aromatic hydrocarbon group or a trivalent heterocyclic group; and X<1> and X<2> are each independently O, S, C(=O), S(=O), SO2, C(R<1>)(R<2>), Si(R<3>)(R<4>), N(R<5>), B(R<6>), P(R<7>), or P(=O)(R<8>), with the provisos that X<1> and X<2> must not be the same and that X<1> and Ar<2> are bonded respectively to the adjacent carbon atoms constituting the aromatic ring of Ar<1>, and X<2> and Ar<1> are bonded respectively to the adjacent carbon atoms constituting the aromatic ring of Ar<2>] (2) [wherein Ar<3> and Ar<4> are each independently a trivalent aromatic hydrocarbon group or a trivalent heterocyclic group; and X<3> and X<4> are each independently N, B, P, C(R<9>), or Si(R<10>), with the provisos that X<3> and X<4> must not be the same and that X<3> and Ar<4> are bonded respectively to the adjacent carbon atoms constituting the aromatic ring of Ar<3>, and X<4> and Ar<3> are bonded respectively to the adjacent carbon atoms constituting the aromatic ring of Ar<4>].
