Ratiometric electrochemical sensors use the ratio of current signal as the output signal and achieve quantitative detection of the target by the change of the ratio of current signal,which has the advantages of good reliability and high repeatability.Metal organic frameworks(MOFs)materials are porous coordination polymers that have attracted much attention from scholars for their structural and performance advantages such as specific surface area,porosity,and pore size.Currently,ratiometric electrochemical sensors based on MOFs materials have been widely used for the detection of a variety of substances and have become a potential alternative to traditional detection methods.Based on this,the principle,classification,common signal substances and properties of different MOFs materials of ratiometric electrochemical sensors were summarized,and the progress of ratiometric electrochemical sensors based on functionalized MOFs materials for detection application were mainly reviewed(60 ref.cited).
