Colorimetric Sensor Array for Amines based on Responsive Lanthanide Complex Entrapment

Abstract

Herein a small sensor array (or artificial tongue) generated by three sensing elements (Eu0.5Tb9.5(HFA)n@ZY, Eu1Tb9(HFA)n@ZY, Eu2Tb8(HFA)n@ZY, HFA: Hexafluoroacetylacetonate) obtained by encapsulating Eu-Tb binuclear complexes within the cavities of zeolite Y (ZY) has been demonstrated, which can accomplish the accurate identification for a group of 13 different amines. As for each of amines, the sensor array generates a unique response pattern, which can be used as a fingerprint to discriminate 13 amine molecules. Additionally, this sensor array has the ability to distinguish the isomers of some amines. Such a work offers a new direction for developing sensitive array sensing for multi-analytes systems and isomers.
