Amine functionalized metal organic frameworks synthesis characterization and applications in fluorescence sensing and photocatalysis

Abstract

MOFs have emerged as a potential class of porous solids synthesized by the co-ordination between the metal ions and organic ligands. Owing to their numerous versatile characteristics, such as tunability, surface area, porosity, etc. MOFs have significant applications in various areas i.e. drug delivery, sensors, photocatalysis, adsorption etc. Inspite of their sensational characteristics, certain drawbacks in native MOFs hinder their applications. Hence, to circumvent these issues, functionalization of MOFs has become the recent thrust area of research, which can be done by altering organic linkers, metal nodes and pore cavities of the framework. Although various functional groups have been incorporated into pristine MOFs to enhance their properties, however, amine functionalized MOFs have received global attention owing to their numerous techno-economic benefits. Amine functionalized MOFs have several applications, specifically in the field of fluorescent sensors used for the detection of organic pollutants and as photocatalysts for the efficient degradation of organic contaminants. Besides, the integration of amine modified MOFs with other functional materials to construct MOFs based heterostructures has also gained significant attraction from researchers. The present work deals with the synthesis, characterization and applications of amine functionalized MOFs and their composites for the detection and degradation of organic contaminants in aqueous phase. newline
