Abstract:
Spin crossover cations have been successfully synthesized in the pores of a mesoporous robust Metal-Organic Framework (MOF) MIL-100(Al) through sequential introduction of Fe(iii) cations and a sal2trien ligand. The MIL-100(Al)@Fe(sal2trien) hybrid material retains its crystallinity and partial porosity compared to the parent MOF. The spin state of the Fe(sal2trien)+ cations can be modulated at room temperature through sorption of guest molecules, paving the way to the design of a new generation of sensors based on MOF@spin crossover complex solids.

Crossover Experiments
Crossover designs are performed even with smaller sample sizes since the samples can act as their controls. These are better than simple randomized trials since patients are exposed to all the treatments.

Qualitatively, any spin plus-half nucleus polarizes the spins of its electrons to the minus-half state. Consequently, the paired electron in the hydrogen–carbon bond must...
