macrocycles made it possible to use them as potentiometric sensor molecules when incorporated into plasticized PVC membrane electrodes. Ligand (R,R)-3 showed appreciable enantioselectivity toward the enantiomers of 1-phenylethylammonium chloride while macrocycle (R,R)-4 exhibited a high selectivity toward the silver ion.
从市售和相对便宜的化学品开始,分别是新的对映体纯的二异丁基和二辛基取代的cri啶基-18-冠-6醚型配体[(R,R)-3 ]和[(R,R)-4 ]。准备好了。这些大环的立体中心上的两个亲脂异丁基[(R,R)-3 ]和辛基[(R,R)-4 ]基团可以在将其掺入增塑的PVC膜电极中时用作电位传感器分子。配体(R,R)-3对1-苯基乙基氯化铵的对映异构体表现出明显的对映选择性,而大环(R,R)-4对银离子表现出高选择性。
