摘要
A new chiral ionic probe for recognition and detection of Cu(Ⅱ) and Pd(Ⅱ) polymer R-poly-6 having pyridine and binaphthyl moietie was synthesized by the Suzuki cross-coupling reaction,which was characterized with element analysis,IR,1H NMR and 13C NMR spectroscopies. The CD and UV-Vis absorption spectra of the complexes of R-poly-6 with PdSO4 and R-poly-6 with CuCl2 in DMSO at room temperature indicated both Pd2+ and Cu2+ have the ability to increase the intensity of CD signal around 268 nm. But in the case of Cu2+,peak shift was observed. It was considered that the different interaction between the complexation of R-poly-6 with PdSO4 and the complexation of R-poly-6 with CuCl2 generated different configuration variation.
A new chiral ionic probe for recognition and detection of Cu （ Ⅱ ） and Pd （ Ⅱ） polymer R-poly-6 having pyridine and binaphthyl moietie was synthesized by the Suzuki cross-coupling reaction, which was characterized with element analysis, IR, ^1H NMR and ^13C NMR spectroscopies. The CD and UV-Vis absorption spectra of the complexes of R-poly-6 with PdSO4 and R-poly-6 with CuCl2 in DMSO at room temperature indicated both Pd^2＋ and Cu^2＋ have the ability to increase the intensity of CD signal around 268 nm. But in the case of Cu2＋ , peak shift was observed. It was considered that the different interaction between the complexation of R-poly-6 with PdSO4 and the complexation of R-poly-6 with CuCl2 generated different configuration variation.
