A family of 3D lanthanide organic frameworks with tunable luminescence and slow magnetic relaxation†
Abstract
A family of 3D lanthanide organic frameworks with 5-(pyridin-4-yl)isophthalic acid (H2PIP), formulated as [Ln2(PIP)3(H2O)4]·2DMF·3H2O (Ln = Sm 1, Eu 2, Gd 3, Tb 4, Dy 5 and Ho 6) have been synthesized and structurally characterized. They are isomorphous and feature a 3D 6-connected pcu topology. The tunable luminescence of 2 and 4 is investigated by changing the temperature and the variation of excitation wavelength. In addition, the slow magnetic relaxation behavior is observed in 5.
