Abstract
High-molecular compounds comprising repeating units represented by the general formula (1) or (2) and having number-average molecular weights of 10to 10in terms of polystyrene: (1) [wherein Arand Arare each independently a trivalent aromatic hydrocarbon group or a trivalent heterocyclic group; and Xand Xare each independently O, S, C(═O), S(═O), SO, C(R)(R), Si(R)(R), N(R), B(R), P(R), or P(═O)(R), with the provisos that Xand Xmust not be the same and that Xand Arare bonded respectively to the adjacent carbon atoms constituting the aromatic ring of Ar, and Xand Arare bonded respectively to the adjacent carbon atoms constituting the aromatic ring of Ar] (2) [wherein Arand Arare each independently a trivalent aromatic hydrocarbon group or a trivalent heterocyclic group; and Xand Xare each independently N, B, P, C(R), or Si(R), with the provisos that Xand Xmust not be the same and that Xand Arare bonded respectively to the adjacent carbon atoms constituting the aromatic ring of Ar, and Xand Arare bonded respectively to the adjacent carbon atoms constituting the aromatic ring of Ar].
