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 electroactive poly(aryl ether ketone) macrocyclic oligmer with phenyl-capped tetramer was synthesized by the modified pseudo-high-dilution method,whose structure with a rigid molecular backbone contains a cavity of well-defined size.The oligomer was characterized with mass spectrometry,IR and 1H NMR,13C NMR spectroscopies.Its redox property was checked by cyclic voltammetry and chemical oxidation process was monitored by UV spectroscopy.We found that it has a reversible electrochemical property like common oligoanilines.Combined with its well-defined structure,the oligmer is expected to act as a kind of host molecules which are capable of molecular recognition.
