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), Van der Veen, M.A. (author)Regioregular poly(3-hexylthiophene)s with chain lengths varying from 5 to 100 monomers are synthesized. Poly(3-hexylthiophene)s show in solution an unexpectedly significant second-order nonlinear optical response. The increase in transition dipole moment upon oligomerisation causes the significant second-order nonlinear optical response.journal article 2014
