Abstract
This review aims to explore the design, development and applications of magnetically supported covalent organic frameworks (MCOFs) in extraction of metal ions, nitro explosives and chemical pollutants.
Highlights
Over the decades, porous materials have gained tremendous attention due to their magnificent potential and broad range of applications in the field of sensing, energy storage, catalysis, energy conversion, gas storage and separation, optoelectronics, etc.[1,2,3] To date, a variety of highly porous materials having large surface area such as hyper-cross-linked polymers, conjugated microporous polymers and polymers with intrinsic microporosity have been designed.[1]
If no hysteresis loop and coercivity or remanence is observed in the curve, it suggests that MagCOF composites are superparamagnetic in nature.[69]
We focus on the synthesis of MagCOFs and their utility as magnetic extractants in various fields in combination with magnetic solid-phase extraction (MSPE)
Summary
Porous materials have gained tremendous attention due to their magnificent potential and broad range of applications in the field of sensing, energy storage, catalysis, energy conversion, gas storage and separation, optoelectronics, etc.[1,2,3] To date, a variety of highly porous materials having large surface area such as hyper-cross-linked polymers, conjugated microporous polymers and polymers with intrinsic microporosity have been designed.[1]. COFs represent a promising class of well-defined porous and crystalline polymeric materials synthesized via condensation reactions of 2D and 3D organic building precursors.[9,10] In general, they are composed of light elements such as hydrogen, boron, oxygen, carbon, nitrogen and silicon which are linked via strong covalent bonds in a reversible manner to generate reticular architecture This thermodynamically controlled and Gunjan Arora was born in India in the year 1992. Anju Srivastava is a Professor of Chemistry and Principal of a premier institution ranked amongst top three in the country, Hindu College, University of Delhi She received her MSc and PhD in Synthetic. In 2002 from Presidency College, Kolkata, India and obtained his MSc in 2004 from Indian Institute of Technology, Kanpur, India He went on to receive his PhD from Cornell University, New York, USA and undertook a few postdoctoral stints in USA, Europe, Czech Republic and joined Vignan’s Foundation for Anandarup Goswami. Synthesis of MagCOFs and the investigation of their in-depth utility in adsorption science has become an area of prime significance in material science
