Terpyridine ligand is a very important functional group for obtaining supramolecular structures and preparing important koordination compounds [1-2]. Numerous important applications such as self-healing materials, shape memory materials, carriers in drug / gene delivery, bioimaging, biodegradable packaging, energy storage, energy conversion, smart polymers and coatings have been realized with molecular architectures prepared using terpyridine ligand structures [1-4]. In addition, multifunctional structures with very important bioactive molecular, magnetic, optical, ferroelectric or catalyst properties have been obtained by combining terpyridine structures and nanostructures [3-5]. In this study, hybrid supramolecular polymeric structures that combine the magnetic properties of the CoFe2O4 structure and the stimulus-response properties of the terpyridine molecule were prepared. Within the scope of the study, CoFe2O4 nanoparticle structure was prepared using co-precipitation technique. The aminofunctional CoFe2O4 structure was obtained by interacting the surface of the obtained nanoparticles with the aminopropyctriethoxy silane structure. The 4-chloro-terpyridine group was attached to the functional magnetic nanoparticle structure. By interacting the terpyridine functional structures obtained in this way with Pd salts, polymeric systems with supramolecular networks were obtained. The structures obtained at each step were structurally confirmed by FTIR spectrum and X-ray. Morphological and surface properties were determined by SEM analysis. In addition, the thermal properties of the obtained structures were determined by TGA, DTA and DSC thermograms. In addition, the stimulus-response properties of the obtained supramolecular polymers were determined by UV spectrophotometer. The resulting metallo-polymers exhibited magnetic properties and strong double absorption bands around 310 nm and 500 nm, located in π-π* transitions and metalligand charge transfer (MLCT) absorption bands. The resulting hybrid supramolecular structures have potential for applications in smart materials production, electronic, optical, magnetic devices, and catalysts.
