Homogeneous and compact monolayer films (ca. 2.5 nm thick) were first formed at the air–water interface, deposited onto different substrates and characterized using spectroscopic methods, scanning transmission electron microscopy and atomic force microscopy. As a proof of concept, the gas separation performance of MOP-supported membranes has also been evaluated. Selective MOP ultrathin films (thickness ca. 60 nm) exhibit remarkable CO2 permeance and CO2/N2 selectivity, demonstrating the great combined potential of MOP and Langmuir-based techniques in separation technologies.2020http://zaguan.unizar.es/record/9705410.1002/chem.201904141http://zaguan.unizar.es/record/97054oai:zaguan.unizar.es:97054info:eu-repo/grantAgreement/ES/DGA/E31-17Rinfo:eu-repo/grantAgreement/ES/DGA/T43-17Rinfo:eu-repo/grantAgreement/EC/FP7/615954/EU/Multifunctional micro- and nanostructures assembled from nanoscale metal-organic frameworks and inorganic nanoparticles/InanoMOFinfo:eu-repo/grantAgreement/ES/MEC/FPU2014info:eu-repo/grantAgreement/ES/MICINN/RTI2018-095622-B-100info:eu-repo/grantAgreement/ES/MINECO/MAT2016-77290-Rinfo:eu-repo/grantAgreement/ES/MINECO/MAT2016-78257-Rinfo:eu-repo/grantAgreement/ES/MINECO/MAT2017-86826-RChemistry - A European Journal 26, 1 (2020), 143-147All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
