Abstract:
Recently, the development of magnetic nanoparticles coated with covalent organic frameworks (MNPs@COFs) has received substantial attention from researchers. Herein, we introduced a straightforward route for the construction of MNPs@COF containing trifluoroacetate (MNPs@COF-TFA), which acts as a heterogeneous catalyst. The synthesized catalyst was characterized using several methods such as Fourier-transform infrared (FT-IR) spectroscopy, field emission scanning electron microscopy (FE-SEM), energy-dispersive X-ray spectroscopy (EDS), elemental mapping analysis, transmission electron microscopy (TEM), X-ray diffraction analysis (XRD), thermogravimetric analysis/derivative thermogravimetry analysis (TGA/DTG), N2 adsorption-desorption analysis and vibrating-sample magnetometry (VSM). Conjunction of the potential application of Fe3O4 and hydrazone-linked COF decorated by trifluoroacetic acid (TFA) propels MNPs@COF-TFA as a robust, stable, recoverable and highly active catalyst for the Doebner reaction. This research underscores the high catalytic activity, easy recovery and reusability of MNPs@COF-TFA, with short reaction times and high yields of target molecules.

Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.

In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
