利用微波合成了一种新型的氮杂冠醚咔唑荧光离子载体1，并利用光谱方法研究了其对金属离子的传感行为。在非缓冲水溶液中，该荧光探针对Fe ~（3+）具有很好的选择性，对背景金属离子（Li ~+、Na ~+、K ~+、Mg ~（2+）、Ca ~（2+）、Al ~（3+）、Cr ~（3+）、Mn ~（2+）、Fe ~（2+）、Ni ~（2+）、Cu ~（2+）、Zn ~（2+）、Cd ~（2+）、Hg ~（2+）、Pb ~（2+）和Ga ~（3+））无干扰。此外，通过电聚合法成功地将这种新的选择性铁探针固定在金电极上，并用EQCM进行了监测。(C)2012 Elsevier B. V.保留所有权利。
A new N-azacrown carbazole fluoroionophore 1 was synthesized by microwave path and its sensing behavior toward metal ions was investigated by spectroscopic methods. This new structure proved to be an excellent selective fluorescent probe toward Fe3+ in non-buffered aqueous solution without interference with the background metal ions (Li+, Na+, K+, Mg2+, Ca2+, Al3+, Cr3+, Mn2+, Fe2+, Ni2+, Cu2+, Zn2+, Cd2+, Hg2+, Pb2+ and Ga3+). Additionally, the immobilization of this new selective iron probe was successfully achieved on gold electrode by electro-polymerization and monitored by EQCM. (C) 2012 Elsevier B.V.
