Abstract
The aim of this investigation is, to utilize coordination-driven self-assembly reactions of 4, 4′-dibromobenzophenone with tetrakis(triethyl phosphine) platinum to construct platinum-containing supramolecular metallacycle, 4, 4′-bis[trans-Pt(PEt3)2Br]benzophenone with exploitable properties for application in catalysis, energy storage, and biomedicine. The process was monitored by 1H NMR and C NMR. A 4, 4’-dibromobenzophenone and tetrakis(triethyl phosphine) platinum in the ratio 1:2 in toluene were utilized in the synthesis. In the structure, platinum ions are coordinated through the bridging ligand molecules forming polymeric chains with a four atomic environment. The coordination environment was that of a square planar geometry with two phosphorus atoms of triethyl phosphine in apical positions. The optimized geometry evaluated by DFT B3LYP-6-311G, Gaussian09W, and Avogadro models support the crystal structure of this molecule. The compound offers high reversible binding properties that can be used for designing smart surfaces for applications in catalysis, energy storage, and biomedicine. The results from the experimental investigation and computer-aided design provide insight into the best strategies, by design, and binding mode. Future works are recommended for developing this discrete supramolecular metallacycle into supramolecular metallacages for its application in the drug delivery system.
