Nanoparticles of mesoporous MIL‐100(Al, Cr or Fe) metal–organic frameworks were synthesized by a microwave‐assisted solvothermal route with green solvents. The optimization of yield, crystallinity, and particle size was achieved through the control of synthetic parameters such as temperature, heating rate, and dwelling time. The particle size strongly depends on the metallic cation and the metal and linker precursors; nanoparticles smaller than 100 nm were obtained for iron and chromium based MIL‐100. Finally, stable colloidal solutions of iron and chromium MIL‐100 nanoparticles were used for thin layer dip‐coating deposition, which resulted in high optical quality thin films, the porosity of which was investigated by environmental ellipsometric porosimetry.
