含联萘基团的手性聚芳醚酮类环状齐聚物修饰电极的制备及其对色氨酸/磷钨杂多酸超分子化合物的手性识别

Preparation of Modified Electrode and Chiral Recognition Properties of PAEK Macrocyclic Oligomer Bearing 1,1′-Bi-2-naphthyl Moiety

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.
