Abstract

Abstract: 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.
