Recent progress in the development of MOF-based optical sensors for Fe3+

Abstract

Fe(III) is a common pollutant released into our ecosystem from various industrial and anthropogenic activities which when in excess interferes with human health. A plethora of sensors based on various designs and working principles are being continuously synthesized and improvised for its facile detection. In the present review, we have provided a brief overview of the developments made in the field of metal organic framework (MOF) based optical sensors for Fe³⁺. MOFs have exponentially emerged in the field of research due to their high porosity, modular construction and easy tunability. These inorganic–organic hybrid porous materials are being essentially promoted as optical sensors because of their unique photophysical properties and potential sensing applications.
