Synthesis and Iodine Adsorption Properties of Organometallic Copolymers with Propeller-Shaped Fe(II) Clathrochelates Bridged by Different Diaryl Thioether and Their Oxidized Sulfone Derivatives

Abstract: Three organometallic copolymers, ICP1-3, containing iron(II) clathrochelate units with cyclohexyl lateral groups and interconnected by various thioether derivatives were synthesized. The reaction of the latter into their corresponding OICP1-3 sulfone derivatives was achieved quantitatively using mild oxidation reaction conditions. The target copolymers, ICP1-3 and OICP1-3, were characterized by various instrumental analysis techniques, and their iodine uptake studies disclosed excellent iodine properties, reac… Show more

“…On the other hand, the absorption bands seen at 1592 and 762 cm −1 are assigned to the aromatic alkene (C�C) stretching and bending vibrations, respectively. 40,41 This corroborates the successful synthesis of conjugated copolymer CAP2. Likewise, copolymers CAP1,3 disclose similar typical peaks, which confirm their structures as well (Figures S15 and S17 in the Supporting Information file).…”

“…Furthermore, the FT-IR spectrum of CAP2 discloses all of the fingerprint peaks, namely, the N–H stretching vibration at 3310 cm –1 and aliphatic C–H and aromatic C–H bending vibrations at 2964 and 1436 cm –1 , respectively. On the other hand, the absorption bands seen at 1592 and 762 cm –1 are assigned to the aromatic alkene (CC) stretching and bending vibrations, respectively. , This corroborates the successful synthesis of conjugated copolymer CAP2 .

“…Indeed, cage complexes of this type with the encapsulated metal ion(s) are known to be chemically robust coordination compounds possessing unusual chemical, optical and redox properties. 3 They have been earlier proposed as prospective “topological” prodrugs, 4 optical probes, 5 homo- and heterogeneous catalysts, 6 covalent and coordination polymers, 7 MOFs 8 and the single-ion molecular magnets 9 with record magnetic characteristics as well. Most of them are formed by the iron( ii )-centered clathrochelate ligands and monomers.…”
