Abstract: As a new type of porous material,metal organic cages (MOCs) possess the characteristics of adjustable geometry,diverse cavity structures,and easy modification.At present, there are many applications in the fields of sensing,catalysis,and molecular recognition.The applications of selective adsorption and chromatographic separation have also attracted great interest from researchers.In this article,the progress of the synthesis of MOCs and their applications were summarized in selective adsorption and chromatographic separation areas in recent years,presenting the prospects of their development.
