The Growth of Metal–Organic Framework Films on Calcium Fluoride and Their Interaction With Reactive Molecules

Spectroscopy on metal–organic framework (MOF) films and the molecular phenomena associated to them is mostly limited grazing incidence methods. To allow for transmission-based characterization highlight applicability of MOFs transparent substrates, UiO-67, UU-1, ZIF-8 are synthesized CaF2 windows. It revealed that growth UiO-67 MOF follows a Volmer–Weber mechanism using scanning electron microscopy (SEM). This assisted by growing seeds in solution, which anchor film become part intergrown itself. copper-based MOF, formed after spin coating Cu-BTC precursors, showing its characteristic fiber-like morphology resulting inter-fiber macroporosity. “flash”-synthesis, it shown this approach resembles mode as well. Last, CO probe molecule adsorption FT-IR spectroscopy utilized study effect methanol exposure. becomes inaccessible toward CO, due formation methoxy species, whereas UU-1 undergoes topotactic transformation HKUST-1. most stable only removes impurities from framework. opens venue other materials be studied situ synthesis, sorption, or catalysis spectroscopy.
