Asymmetric Design of Spin-Crossover Complexes to Increase the Volatility for Surface Deposition

May 2, 2024September 2, 2021 by Eric Switzer

A mononuclear complex [Fe(tBu2qsal)2] has been obtained by a reaction between an Fe(II) precursor salt and a tridentate ligand 2,4-di(tert-butyl)-6-((quinoline-8-ylimino)methyl)phenol (tBu2qsalH) in the presence of triethylamine. The complex exhibits a hysteretic spin transition at 117 K upon cooling and 129 K upon warming, as well as light-induced excited spin-state trapping at lower temperatures. Although the … Read more

On stabilizing spin crossover molecule [Fe(tBu2qsal)2] on suitable supports: insights from ab initio studies

May 2, 2024July 21, 2021 by Eric Switzer

Au(111) is one of the substrates often used for supporting spin crossover (SCO) molecules, partly because of its inertness and partly because it is conducting. Using density functional theory based calculations of [Fe(tBu2qsal)2] SCO molecules adsorbed on the Au(111) surface, we show that while Au(111) may not be a suitable support for the molecule, it … Read more
