A polymer compound comprising a repeating unit represented by the formula (1) or (2) and having a number average molecular weight in terms of polystyrene of 10 3 to 10 8 .n n n <Formula 1>n n n n n n n n (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), SO 2 , C (R 1 ) (R 2 ), Si (R 3 ) (R 4 ), N (R 5 ), B (R 6 ), P (R 7 ) or P (= O) (R 8 ) It denotes a. X 1 and X 2 are not the cases in which the same. in addition, X 1 and Ar 2 is bonded to the adjacent carbon in the aromatic ring of Ar 1, and, X 2 and Ar 1 are the adjacent carbon in the aromatic ring of Ar 2 To combine.)n n n <Formula 2>n n n n n n n n (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). ) to indicate there is no cases in which the X 3 and X 4 the same. in addition, X 3 and Ar 4 are bonded to the adjacent carbon in the aromatic ring of Ar 3 and, X 4 and Ar 3 are adjacent in the aromatic ring of Ar 4 carbon To bind.) |
