摘要：
A series of lanthanide(III) complexes Ln(H2L) . (HL) .0.5(bipy).nH(2)O (where Ln = Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Er, Yb, and H3L = N-(2-propionic acid)-salicyloyl hydrazone, bipy = 2,2'-dipyridine) have been synthesized in ethanol-water mixture and characterized. The DNA-binding properties of these complexes were searched for the interaction with CT-DNA by electronic absorption titration and emission titration. The results showed that the interaction between Nd(III) complex and CT-DNA by surface/electrostatic binding, while all the other complexes can bind to calf-thymus DNA mainly by intercalation mode.
