Highly Luminescent Crystalline Sponge: Sensing Properties and Direct X-ray Visualization of the Substrates.

ABSTRACT: A phenomenon of crystalline sponge is represented by guest-dependent structural fluidity of the host polymeric lattice in highly crystalline sorbents, such as metal-organic frameworks, driven by multiple weak intermolecular interactions. Such induced fitting in MOFs is a valuable property in selective adsorption, guest determination by single-crystal XRD and in-situ structural analysis under external stimuli. In this work, a porous three-dimensional metal-organic framework [Eu₂(DMF)₄(ttdc)₃]·4.45DMF (1_DMF; DMF = N,N-dimethylformamide, ttdc^2- = trans-thienothiophenedicarboxylate anion) was applied as a crystalline sponge bearing luminescent functionality to couple its sensing properties with direct structural determ
