Metal organic framework is a kind of three-dimensional framework porous materials self-assembly by a structure of organic ligands and metal centers. Because of the structure of metal organic complex framework, it has good chemical properties. Metal-organic frameworks have become more and more mature when applied to material analysis. Significant progress has also been achieved in the application of electrochemical sensors. In this paper, the newly found preparing approaches to the mental-organic frameworks, constructing electrochemical sensor methods as well as the summary of its application in electrochemical sensor based on MOF are presented. The problems and the limitations in metal-organic frameworks application to the electrochemical sensors are also involved. At the end, we briefly discuss the direction and expectations of electrochemical sensor based on metal-organic frameworks.
