Europium(iii)/terbium(iii) mixed metal-organic frameworks and their application as ratiometric thermometers with tuneable sensitivity in organic dispersion.

ABSTRACT: The ability to engineer on a molecular level luminescent metal-organic frameworks (MOFs) enables the design of well-performing ratiometric, i.e., self-referencing, temperature sensors. Lanthanide-based MOFs stand out as luminescent temperature sensors due to their high luminescence intensity and the sharp emission lines of the lanthanides. The use of two different lanthanide cations, incorporated into the same MOF structure, is supposed to enable ratiometric temperature sensing. Herein, we present a series of mixed-metal Eu _x Tb_(1-x)BTC, in which the metal ions are homogeneously dispersed, as demonstrated by ¹H solid state NMR spectroscopy. The Eu _x Tb_(1-x)BTC series shows controllable luminescent pro
