Second harmonic generation microscopy reveals hidden polar organization in fluoride doped MIL-53(Fe)Markey, K. (author), Putzeys, T. (author), Horcajada, P. (author), Devic, T. (author), Guillou, N. (author), Wübbenhorst, M. (author), Van Cleuvenbergen, S. (author), Verbiest, T. (author), De Vos, D.E. (author), Van der Veen, M.A. (author)Polar metal–organic frameworks have potential applications as functional non-linear optical, piezoelectric, pyroelectric and ferroelectric materials. Using second harmonic generation microscopy we found that fluoride doping of the microporous iron(III) terephthalate MOF MIL-53(Fe) induces a polar organization in its structure, which was not...journal article 2016

(author), Kapteijn, F. (author), Gascon, J. (author)In this work, the inclusion of free sulfonic acid groups in highly stable MOFs is explored. The synthesized catalysts have been applied in a model esterification reaction. Two metal organic frameworks bearing sulfonic acid moieties are investigated: HSO3-MIL-101(Cr) synthesized following different approaches and a new structure based on HSO3-bdc...journal article 2013
