X1 and X2 each independently represent O, S, C(═O), S(═O), SO2, C(R1)(R2), Si(R3)(R4), N(R5), B(R6), P(R7) or P(═O)(R8). X1 and Ar2 bond to adjacent carbon atoms in the aromatic ring of Ar1; and X2 and Ar1 bond to adjacent carbon atoms in the aromatic ring of Ar2]; [wherein Ar3 and Ar4 each independently represent a trivalent aromatic hydrocarbon group or a trivalent heterocyclic group. X3 and X4 each independently represent N, B, P, C(R9) or Si(R10). X3 and Ar4 bond to adjacent carbon atoms in the aromatic ring of Ar3; and X4 and Ar3 bond to adjacent carbon atoms in the aromatic ring of Ar4].
