对一系列专门用于 Mg(II) 离子检测的 diaza-18-crown-6 8-羟基喹啉 (DCHQ) 化学传感器进行了系统研究。通过外围取代基对 DCHQ 进行功能化，可以通过将其包含在 PVC 基聚合物薄膜中来开发新型全固态光极。研究了亲脂位点功能化和增塑剂性质对基于 DCHQ 的光极响应的影响。对光极对多种不同金属阳离子（Ca2+、Na+、K+、Li+、Co2+、Cd2+、Pb2+、Cu2+、Hg2+、Zn2+）和 NH4(+) 的敏感性进行了荧光研究。结果证明了 DCHQ 光极适合执行快速监测（
A systematic study of a series of diaza-18-crown-6 8-hydroxyquinoline (DCHQ) chemosensors, devoted to Mg(II) ion detection, was performed. Functionalization of DCHQ by peripheral substituents allowed the development of novel all-solid-state optodes via inclusion inside PVC-based polymeric films. The influence on the DCHQ-based optode response of the lipophilic sites functionalization and of the nature of the plasticizer, was investigated. Fluorimetric studies on optodes sensitivity towards a number of different metal cations (Ca2+, Na+, K+, Li+, Co2+, Cd2+, Pb2+, Cu2+, Hg2+, Zn2+) and NH4(+) were carried out. The results demonstrated the suitability of the DCHQ optodes to perform fast monitoring (
