Solvent vapor-induced polarity and ferroelectricity switching

Solvent vapor-induced polarity and ferroelectricity switching

Vapor-induced crystal to crystal transformation between non-polar [Fe(sap)(acac)(sol)] (H 2 sap = 2-salicylideneaminophenol, acac = acethylacetate, sol = MeOH, pyridine) and polar [Fe(sap)(acac)(DMSO)] was demonstrated. It provides an example of switchable ferroelectric behaviour attributted to the...

Zusammenfassung:Vapor-induced crystal to crystal transformation between non-polar [Fe(sap)(acac)(sol)] (H 2 sap = 2-salicylideneaminophenol, acac = acethylacetate, sol = MeOH, pyridine) and polar [Fe(sap)(acac)(DMSO)] was demonstrated. It provides an example of switchable ferroelectric behaviour attributted to the structural phase transition triggered by solvent vapour. A new example of vapor-induced reversible polarity and ferroelectricity switching system has been demonstrated in mononuclear iron( iii ) complexes.
