Synthesis of a novel fluorescence sensitive Fe(II) spin crossover system

Abstract

Multifunctional spin crossover (SCO) compounds – with promising and versatile applications – combine classic SCO properties with additional features e.g. non-linear optics, bulk magnetic ordering, etc. Since SCO compounds are frequently used as nanomaterials, a promising approach to easily detect the spin state of a system – even in small clusters – is the spin state-dependent modulation of photoluminescence (PL). Investigations regarding combined SCO-PL systems are not only interesting for possible future applications, but also because the mechanism behind this phenomenon is not yet completely understood.
