Cpds. of formula I-(T)m (I) and their acid addn. salts are new. Where, I = (hetero)aromatic segment; T is of formula (II), if n is greater than 1; X = N or S; R, R1 and R2 = alkyl, (hetero)alicyclic or (hetero)aromatic gps.; R3 and R4 = H if X = N; Me, Et or Ph if X = 5; K and q = 0-10; n = 2-20; m = 1-5; o and p = 0 or 1; I is not phenanthridium when X = N; R3 = R4 = H and (a) R, R1 and R2 = CH2; o = p = m = 1; (b) R, R1 and R2 = CH2, o = 1; p = 1, m = 2; a first T is bonded directly to I in which n = 2, k = 1 and q = zero, and a second T (directly bonded to the first T) has n = 2, k = q = zero; or n = 2, k = q = 1; (c) o = p = K = 1; m = 3; n = 2 and q = zero. |
