We predict that the thermal and photo-induced bistability in spin crossover (SCO) core-shell nanoparticles is strongly dependent on the heterostructure geometry. We show that varying the core-shell lattice mismatch allows systematic control of the properties of SCO nanoparticles. We demonstrate a linear relationship between the temperature characterising the photo-induced bistability, TLIESST, and the thermal spin crossover temperature, T1/2. This nanostructural approach complements the traditional approach of controlling the relationship between TLIESST and T1/2 by making chemical substitutions within families of SCO materials. We give a simple explanation of both relationships. We also demonstrate a non-monotonic dependence of thermal hysteresis width on the shell thickness, which explains a number of apparently contradictory experimental observations.

When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
