Sensing of Disinfection Byproducts; An Iodo-Functionalized Metal-Organic Framework as a Platform

Abstract

Abstract A systematic sensing of halogenated disinfection byproducts (DBPs) has been studied for the first time in a un-/ functionalized UiO-67 MOFs. In this regard, an iodo-functionalized UiO-67 type metal-organic framework (MOF) (UiO-67(I)2) has been successfully synthesized via solvothermal reaction. The results show that the sensing response of the MOFs toward halogenated DBPs significantly increased by incorporation of halogen bonding (XB) functionalities. Noteworthy, in each class of DBPs, the sensing response of the considered MOFs regularly improved by moving from fluoro to iodo group; which precisely indicates that halogen bonding is in charge.
