Abstract The surface coating of porous materials is a technically important subject. In this study, using this point, we demonstrate a fast and controllable method for fabrication of porous metal-organic frameworks(MOFs) flims and use these films for surface-enhanced IR detection of benzene. Specifically, we synthesized nanocrystalline nMOFs, and used their colloidal dispersion to make nMOFs films by spin-coating process. After finding high sorption property of benzene in nMOFs , the nMOFs film formed on plasmonic Au substrates was successfully applied to the detection of benzene using surface-enhanced IR spectroscopy. These results indicate that our method to make a porous thin film of MOFs on the plasmonic substrate provide a facile way to observe gas molecules using the surface-enhanced IR detection and possibilities to further investigate their reaction mechanism using enhanced in-situ IR signals. This is the first case of making nMOF particle coating on a plasmonic substrate for surface enhanced IR detection of volatile organic compounds(VOCs).
