Ultrathin hydrophobic films based on the metal organic framework UiO-66-COOH(Zr).

ABSTRACT: This work reports on the fabrication, optimization and characterization of ultrathin films containing submicrometer particles (sMPs) of the hydrophilic and water stable UiO-66-COOH(Zr) metal organic framework (MOF). MOF particles of ≈200 nm have been synthesized and assembled at the air-water interface by the Langmuir-Blodgett technique. The use of different solvents, mixtures of solvents and surfactants has been investigated in order to improve the stability of MOF dispersions and reduce particle aggregation. The compact MOF/surfactant films containing 10 wt % octadecylphoshonic acid (ODP) have been deposited on substrates of different nature by Langmuir-Blodgett (LB) and Langmuir-Schaefer (LS) methods, showing that the presence of even only one MOF/ODP monolayer can increase the water co
