TL;DR: It is demonstrated that surface plasmon polariton waves propagating along the interface between a metal and a dielectric layer can be used to detect the spin-state changes in the latter with high sensitivity, even at the nanometer scale.

TL;DR: Results show that molecular spin state switching can be very efficiently triggered by the photo-thermal effect, which - in turn - allows for an active tuning of the plasmon resonance.

TL;DR: In this article, the authors examined different optical spectroscopic approaches for the detection of spin-state changes in nanometric films and found that conventional light absorption measurements can be used down to the nanometer thickness if the oscillator strength of the transition is high, which is often the case for charge transfer transitions in the ultraviolet range.

TL;DR: While the grating thickness had no influence on the spin-crossover properties of the gratings, the adsorption of aromatic guest molecules was found to have a substantial effect both on thespin transition temperature and the completeness of the transition.

TL;DR: In this paper, the authors discuss the elaboration, optical properties and possible applications of thin films and nano-patterns of molecular spin crossover complexes, and discuss three photonic application principles based on fluorescence energy transfer, grating diffraction and guided plasmon-polariton waves.
