Abstract
Though the first spin crossover (SCO) complex was discovered in 1930s, and this phenomenon has become one of the most studied aspects of molecular bistability, this research area continues to attract significant attention due to its intriguing properties and potential applications. Herein, we report a series of SCO complexes, encompassing mono-, and binuclear complexes, as well as the complexes designed for surface functionalization achieved through careful modification of 2,2′-biimidazole (BIM). In addition, we introduce a simple method for predicting the spin state of homoleptic complexes of the Fe(II) d6 ion with chelating diimine ligands; and a simple route to combine the SCO behavior and other desirable properties, such as conductivity, at the molecular level to make multifunctional materials.
