<p>A polymer compound comprising a repeating unit of below formula (1) or (2), and having a polystyrene reduced number average molecular weight of 10<3> to 10<8>, <CHEM> (wherein, Ar<1> and Ar<2> each independently represent a trivalent aromatic hydrocarbon group or a trivalent heterocyclic group. X<1> and X<2> each independently represent 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>). X<1> and X<2> are not the same. X<1> and Ar<2> bond to adjacent carbons in the aromatic ring of Ar<1>, and X<2> and Ar<1> bond to adjacent carbons in the aromatic ring of Ar<2>), <CHEM> (wherein, Ar<3> and Ar<4> each independently represent a trivalent aromatic hydrocarbon group or a trivalent heterocyclic group. X<3> and X<4> each independently represent N, B, P, C(R<9>) or Si(R<10>). X<3> and X<4> are not the same. X<3> and Ar<4> bond to adjacent carbons in the aromatic ring of Ar<3>, and X<4> and Ar<3> bond to adjacent carbons in the aromatic ring of Ar<4>.).</p> |
