A spin crossover porous hybrid architecture for potential sensing applications

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 sal 2 trien ligand. The MIL-100(Al)@Fe(sal 2 trien) hybrid material retains its crystallinity and partial porosity compared to the parent MOF. The spin state of the Fe(sal 2 trien) + 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.
