Reusable magnetic catalysed synthesis of fluorescent imidazole derivatives: Their use as chromogenic and fluorogenic probes for metal cation's detection

A Novel Recyclable Magnetic Nano-Catalyst for Fenton-Photodegradation of Methyl Orange and Imidazole Derivatives Catalytic Synthesis

“…Figure 2 depicts the graph of cotton (a), 6-CDC (b), and (CDC@Fe 3 O 4 ) (c). The cotton spectrum shows the appearance of two characteristic bands around 883 and 1678 cm −1 , ascribed to the stretching and bending vibrations of C–Cl, respectively [ 25 ]. These changes confirm the substitution of hydroxyl groups by chlorine atoms in (6-CDC) [ 25 ].…”

“…The cotton spectrum shows the appearance of two characteristic bands around 883 and 1678 cm −1 , ascribed to the stretching and bending vibrations of C–Cl, respectively [ 25 ]. These changes confirm the substitution of hydroxyl groups by chlorine atoms in (6-CDC) [ 25 ]. The intense band recorded at approximately 590 cm −1 is ascribed to the Fe-O stretching vibration [ 47 ].…”

“…The average (CDC@Fe 3 O 4 ) nanocomposite size was estimated to be 88 nm using the Scherrer equation: D = K λ / β cos θ where D is the crystallite size, K is the crystallite shape factor (K = 0.94), k corresponds to the X-ray incident wavelength, β denotes the adapted FWHM referring to the full width at half maximum of the corresponding highest intensity recorded diffraction, and h symbolises the diffraction angle (2h = 35.52°) [ 25 ].…”

“…Similarly, Multi-Component Reactions (MCRs) are accustomed to the standards of environmental chemistry aimed at reducing the generation of harmful waste [ 25 ]. Indeed, magnetically modified cellulose derivatives are gaining increasing interest in the field of organic synthesis because of the higher odds of increasing molecular structural diversifications [ 26 , 27 , 28 ].…”
