Abstract: A kind of Ce(Ⅲ) complex with TTA4·HP(TTA=2-Thenoyltrifluoroacetone, HP=Piperidine) has been synthesized and characterized. DNA-binding properties of CeTTA4·HP were investigated using UV spectra, fluorescent spectra, thermal denaturation, CV(cyclic voltammetry), viscometry and molecular modeling. The results showed that the binding-mode between CeTTA4·HP and DNA is intercalation. |
Keywords: 2-thenoyltrifluoroacetone-piperidine Ce(Ⅲ) complex crystal structure spectra DNA-binding properties |
