A Multifunctional Dual-Luminescent Polyoxometalate@Metal-Organic Framework EuW₁₀@UiO-67 Composite as Chemical Probe and Temperature Sensor.

ABSTRACT: The luminescent [EuW₁₀O₃₆]^9- polyoxometalate has been introduced into the cavities of the highly porous zirconium luminescent metal-organic framework UiO-67 via a direct synthesis approach, affording the EuW₁₀@UiO-67 hybrid. Using a combination of techniques (TGA, BET, elemental analysis, EDX mapping,…) this new material has been fully characterized, evidencing that it contains only 0.25% in europium and that the polyoxometalate units are located inside the octahedral cavities and not at the surface of the UiO-67 crystallites. Despite the low amount of europium, it is shown that EuW₁₀@UiO-67 acts as a solid-state luminescent sensor for the detection of amino-acids, the growth of the emission intensity globally following the growth of t
