mesoporous lanthanide-based metal–organic framework (Ln-MOF)
was synthesized. More importantly, its loading capacity for Mn12Ac reached 40.15
mol %, which is not only larger than that reported for porous materials
to date thus far but also significantly larger than that observed
on the surface of LB film. Investigations on the crystal structures
and the nitrogen adsorption isotherms reveal that the well-matched
porous size with that of SMMs in MOFs, the flexible porosity of the
MOFs, and the interactions between MOFs and SMMs are key for enhancing
the loading capacity for SMMs in the MOFs.
