The article describes novel electrochromic materials (ECMs) that are based on a monolayer consisting of two or three isostructural metal complexes of 4′-(pyridin-4-yl)-2,2′:6′,2′′-terpyridine simultaneously deposited on surface-enhanced support. The support was made by screen printing of indium tin oxide (ITO) nanoparticles on ITO-glass and has a surface area sufficient for a monolayer to give color visible to the naked eye. The ability to sep. electrochem. address the oxidation state of the metal centers on the surface (i.e., Co2+/Co3+, Os2+/Os3+, and Fe2+/Fe3+) provides an opportunity to achieve several distinct color-to-color transitions, thus opening the door for constructing monolayer-based multicolor ECMs. The results came from multiple reactions, including the reaction of 4′-(4-Pyridyl)-2,2′:6′,2”-terpyridine(cas: 112881-51-3Reference of 4′-(4-Pyridyl)-2,2′:6′,2”-terpyridine)
4′-(4-Pyridyl)-2,2′:6′,2”-terpyridine(cas: 112881-51-3) belongs to pyridine derivatives. The ring atoms in the pyridine molecule are sp2-hybridized. The nitrogen is involved in the π-bonding aromatic system using its unhybridized p orbital. Reference of 4′-(4-Pyridyl)-2,2′:6′,2”-terpyridineThe lone pair is in an sp2 orbital, projecting outward from the ring in the same plane as the σ bonds.
