EPR in Research of the Magnetic Properties of Spin-Crossover Fe(III) Complexes with Polydentate Schiff Bases

Abstract

Schiff bases allow the creation of compounds with a wide variety of architectures and properties and have been of interest to researchers for many years. This mini-review describes some of the possibilities of the EPR method, which we use to study Fe(III) complexes with polydentate Schiff bases, many of which have been synthesized for the first time. Obtaining information at the local level using EPR spectroscopy allows us to grasp the molecular structure–property relationship and to adjust the synthesis strategy to create multifunctional substances with predetermined properties.
