基于离子选择性膜（ISM）制备了电位传感器件，所述离子选择性膜含有并入聚合物膜中的Hamilton型受体。这些设备的测量能力进行了评估，并在几个不同的含水基质中表现出近能斯特灵敏度，证明了汉密尔顿受体的效用在聚合物膜内的电位检测水中的巴比妥酸盐。这项工作还调查了受体preorganization对传感器性能的影响，并将这些影响与溶液中类似受体系统的观察结果进行了比较。
Potentiometric sensing devices were prepared based on ion-selective membranes (ISM) containing Hamilton-type receptors incorporated into polymer membranes. Measurement capabilities of these devices were evaluated and exhibit near-Nernstian sensitivities in several different aqueous matrices, demonstrating the utility of Hamilton receptors within polymer membranes for potentiometric detection of barbiturates in water. This work also investigates the effects of receptor preorganization on sensor performance and compares these effects to those observed for similar receptor systems in solution.
