A novel MOF has been synthesized, characterized, and applied in the cyanosilylation of aldehydes and ketones being the first example of an yttrium MOF able to catalyze this reaction.

Herein, to the best of our knowledge, the first heterobimetallic Y/Eu porous metal–organic framework (MOF), based on 3-amino-4-hydroxybenzoic acid (H2L) ligand, with the following formulae {[Y3.5Eu1.5L6(OH)3(H2O)3]·12DMF}n (in advance, namely Y/Eu-MOF), is described. The three-dimensional structure has been synthesized by solvothermal routes and thoroughly characterized, by means of single crystal X-ray diffraction, powder X-ray diffraction, electronic microscopy, ICP-AES, electrophoretic mobility, and FTIR spectra. Intriguingly, the porous nature allows for coordinated solvent molecules displacement, yielding unsaturated metal centers, which can act as a Lewis acid catalyst. This novel supramolecular entity has been tested in cyanosilylation and hydroboration reactions on carbonyl substrates of a diverse nature, exhibiting an extraordinary activity.

Herein, we describe and study a new family of isostructural multifunctional metal–organic frameworks (MOFs) with the formula {[Ln 5 L 6 (OH) 3 (DMF) 3 ]·5H 2 O} n (where (H 2 L) is 3-amino-4-hydroxybenzoic acid ligand) for magnetism and photoluminescence. Interestingly, three of the materials (Dy-, Er-, and Yb-based MOFs) present single-molecule magnet (SMM) behavior derived from the magnetic anisotropy of the lanthanide ions as a consequence of the adequate electronic distribution of the coordination environment. Additionally, photoluminescence properties of the ligand in combination with Eu and Tb counterparts were studied, including the heterometallic Eu–Tb mixed MOF that shows potential as ratiometric luminescent thermometers. Finally, the porous nature of the framework allowed showing the CO 2 sorption capacity.

Solvothermally promoted assembly of the multifunctional 3‐amino‐4‐hydroxybenzoic acid ligand with the corresponding Eu salt gives rise to the formation of a porous metal‐organic framework with the general formula {[Eu5L6(OH)3(H2O)3] ⋅ 5DMF}n (1) that has been tested as heterogeneous catalyst for the cyanosilylation of a broad scope of ketones in solvent‐free conditions, using the lowest catalyst loading of 0.5 mol% ever reported, and exhibiting no leak and high recyclability.

SMM behavior and intense photoluminescence are reported for eleven dinuclear and tetranuclear compounds.
