摘要
用溶剂诱导的含联萘基团的手性聚芳醚酮类环状齐聚物(S-PENEKC)制备修饰电极,利用循环伏安法实现了对D,L,DL-色氨酸/磷钨杂多酸的超分子化合物(D,L,DL-H3Trp2-[PW12O40])的手性识别.
Modified electrode of poly（aryl ether ketone） macrocyclic oligomer containing 1, 1＇-bi-2-naphthyl moiety was successfully prepared, which was used to recognize chiral supramolecules that were derived from tryptophan and tungstophosphoric acid （D, L, DL-H3 Trp2-[ PW12O40 ]/GC in 1.0 mol/L H2SO4 ） by the cyclic voltammogram method. By means of vibrational circular dichroism spectroscopy, we found that different solvents treatment could alter the plane angle of the two naphthyl groups （ i. e. , dihedral angle） of S-PENEKC. Therefore, the selectivity of chiral recognition based on S-PENEKC could be achieved by different solvents treatment, which was approved by the results from electrochemical experiments.
