Solvent-Free Encapsulation at High Pressure with Carboxylate-Based MOFs 2019 Access copy available to the general public Unrestricted The solvent-free encapsulation of caffeine and kojic acid was carried out in different carboxylate-based MOFs [MIL-53(Al), UiO-66 and Mg-MOF-74] by high pressure (0.32 GPa) contact. This methodology enables fast and ecofriendly encapsulation and gives rise to additive@MOFs with physical and features equivalent to those of materials obtained by common liquid phase encapsulation processes. It could be applied to other host–guest systems, simplifying the procedures, reducing the use and waste of harmful chemicals, and approaching the conditions of interest in the industry. The characterization carried out by thermogravimetry, X-ray diffraction, N2 adsorption, and 13C NMR provided information about the presence and conformation of the additives in the MOFs. The highest encapsulation values for caffeine (37 %) and kojic acid (32 %) were obtained with MIL-53(Al). info:eu-repo/grantAgreement/ES/DGA-FSE/T43-17R info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.529 2019 CHEMISTRY, INORGANIC & NUCLEAR 16 / 45 = 0.356 2019 Q2 T2 0.693 2019 Inorganic Chemistry 2019 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0003-2006-1495 Paseta, L.
