title: [Synthesis and characterization of La(III) binuclear complex with 2-hydroxy-l-naphthaldehyde-beta-alanine and its interaction with DNA].
abstract: The binuclear complex of Schiff base C14H12NO3K(KHL) derived from 2-hydroxy-l-naphthaldehyde and beta-alanine with lanthanide nitrate was synthesized and characterized by elemental analysis, IR, UV, TG-DTA, and molar conductance analysis. The composition of the complex was [La2(L)2 (NO3)2] x 2C2H5OH. The interaction of the complex and DNA was studied by fluorescence spectrum. The result indicates that the La(III) complex could cause a sharp decrease in the fluorescence intensity of EB-DNA system, and the complex could partly sustain the place of EB.
