Synthetic Route of 89972-76-9, Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 89972-76-9, Name is 4′-(4-Bromophenyl)-2,2′:6′,2”-terpyridine,introducing its new discovery.
A heterometallo-supramolecular polymer with CuI and FeII ions introduced alternately
A new heterometallo-supramolecular polymer with alternating CuI and FeII ions (polyCuFe) was synthesized by simple 0.5:0.5:1 complexation of CuI and FeII salts with an unsymmetrical ditopic ligand (L1) bearing phenanthroline and terpyridine moieties as the metal coordination sites. Selective complexation was confirmed by UV/Vis spectroscopic titration experiments, and the alternate alignment of the two metal ions in polyCuFe was supported by ESI-MS data. Cyclic voltammetry of a polyCuFe film showed two reversible redox waves at 0.29 and 0.78 V vs. Ag/Ag+ based on the redox of CuI/CuII and FeII/FeIII, respectively. Each oxidation state was successfully observed by acquisition of XPS spectra. A solid-state display device was fabricated using the polymer film and a gel electrolyte. The device showed multi-colour electrochromic behaviour by changing an applied potential, based on the different redox potentials of the two metal ions.
