X-ray spectroscopy: Substoichiometric encapsulation of polyoxometalate ions into a metal–organic framework results in a fully functional cation exchanger with accessible porosity. Cu2+ cations compensating the charge of [PW12O40]3− in the as-synthesized material can be exchanged with cations such as Na+ and Eu3+. When exchanged with Eu3+, the material appears bright red under UV irradiation (see figure).
