“…Macrocyclic Schiff bases and their metal complexes have constituted a eld of research in continuous development thanks to their appreciable role based on features of cavity size, rigidity and tendency to establish transition metal complexes which have attracted the interest of the coordination and bioinorganic chemists [1][2][3][4][5]. The synthesis of macrocyclic ligands Schiff bases tetradentates, and their transition metal complexes have been widely studied due to their attractive chemical properties and biological activities [6][7][8][9] and the presence of amino groups similar to the natural biological structure like Hemoglobin and chlorophyll [10,11]. In fact, macrocyclic Schiff bases are particularly important in macrocyclic chemistry because of their exible synthesis, their selectivity, and even their ability to stabilize many metals in various oxidation states [12][13][14][15][16].…”

“…In fact, macrocyclic Schiff bases are particularly important in macrocyclic chemistry because of their exible synthesis, their selectivity, and even their ability to stabilize many metals in various oxidation states [12][13][14][15][16]. However, a huge number of tetraaza macrocyclic (N 4 ) metal complexes show interesting biological activities such as antifungal [17,18], antibacterial [19][20][21], antimicrobial [22][23][24][25] and anticancer [11,26,27] effects.…”

This work presents a simple synthesis of tetraaza macrocyclic Schiff base ligand (C 40 H 28 N 4 ), its complex [(C 40 H 28 N 4 )@Fe(II)], and a novel complex of magnetite Fe 3 O 4 NPs incorporated inside tetraaza macrocyclic cavity [(C 40 H 28 N 4 )@Fe 3 O 4 NPs] in order to obtain welldispersed nanoparticles. The characterization and structural identi cation were carried out by 1 H NMR, 13 C and DEPT 135 NMR spectroscopy as well by X-ray spectroscopy, FT-IR, and nally by ATG using both experimental and theoretical methods. XRD measurements indicate that the presence of Schiff's bases does not modify the crystal structure of the nanoparticles (approximately 11 nm). FT-IR was used to illuminate the presence of Fe 3 O 4 NPs in tetrahedral and octahedral sites as well as their coordination with imine (C=N) of tetraaza macrocyclic. The UV-Vis spectra and frontier molecular orbitals (FMOs) of the title compounds were calculated at TD-DFT/CAM-B3LYP-D3/6-311 G (d, p) level of theory. The corresponding calculated results yield shows a good agreement with the experimental data. The morphological characterization of the nanoparticles was carried out by SEM which revealed that the shape of the NPs was generally spherical. The SEM images also show that the nanoparticles prepared by in-situ with co-precipitation method were able to form stable complexes. Thermal characterization by ATG shows that there is 64% of the magnetite nanoparticles formed in-situ which corresponds to a grafting density of 25 mmol.g −1 .
