“…The reaction was successfully scaled up, proven both visually and by SCXRD, however the framework is not stable to solvent loss as demonstrated by a change in PXRD pattern, highlighting the decomposition (Figure S3). Structurally analogous MOFs have been prepared from Ce, Eu, and Tb, which also decompose in air (Wang et al, 2002), although a Nd derivative has shown sufficient stability to allow gas uptake, with S BET = 150 m 2 g −1 (Wang et al, 2015).…”

Metal-organic frameworks (MOFs)—network structures built from metal ions or clusters and connecting organic ligands—are typically synthesized by solvothermal self-assembly. For transition metal based MOFs, structural predictability is facilitated by control over coordination geometries and linker connectivity under the principles of isoreticular synthesis. For rare earth (RE) MOFs, coordination behavior is dominated by steric and electronic factors, leading to unpredictable structures, and poor control over self-assembly. Herein we show that coordination modulation—the addition of competing ligands into MOF syntheses—offers programmable access to six different Y(III) MOFs all connected by the same naphthalene-2,6-dicarboxylate ligand, despite controlled synthesis of multiple phases from the same metal-ligand combination often being challenging for rare earth MOFs. Four of the materials are isolable in bulk phase purity, three are amenable to rapid microwave synthesis, and the fluorescence sensing ability of one example toward metal cations is reported. The results show that a huge variety of structurally versatile MOFs can potentially be prepared from simple systems, and that coordination modulation is a powerful tool for systematic control of phase behavior in rare earth MOFs.

“…From the design point of view, 2,6-naphtalenedicarboxylate (H 2 NDC) has been employed as suitable ligand for preparing MOFs based on lanthanides 47,48,49,50,51,52 or d-block elements. 53 In this work, we showcase a new set of 3D-frameworks based on H 2 NDC and Ln 3+ ions-from La 3+ to Yb 3+ (save Pm 3+ , Gd 3+ , Ho 3+ and Tm 3+ ) yielding three sets of structures.…”

Tunable Energy-Transfer Process in Heterometallic MOF Materials Based on 2,6-Naphthalenedicarboxylate: Solid-State Lighting and Near-Infrared Luminescence Thermometry

Trivalent lanthanide ions (Ln 3+ ) are used to prepare a plethora of coordination compounds; metal-organic frameworks (MOFs) being amongst the most sought-after in recent years. The porosity of Ln-MOFs is often complemented by the luminescence imparted by the metal centers, making them attractive multifunctional materials. Here, we report a class of 3D MOFs obtained from solvothermal reaction between 2,6-naphtalenedicarboxylic acid (H 2 NDC) and lanthanide chlorides yielding three types of compounds depending on the chosen lanthanide: [LnCl(NDC)(DMF)] for Ln 3+ = La 3+ , Ce 3+ , Pr 3+ , Nd 3+ , Sm 3+ (type 1), [Eu(NDC) 1.5 (DMF)]•0.5DMF (type 2), and [Ln 2 (NDC) 3 (DMF) 2 ] (type 3) for Ln 3+ = Tb 3+ , Dy 3+ , Y 3+ , Er 3+ , Yb 3+ . Photoluminescent properties of selected phases were explored at room temperature. The luminescence thermometry capability of Yb 3+ -doped Nd-MOF was fully investigated in the 15-300 K temperature range under 365 and 808 nm excitation. To describe the optical behavior of the isolated MOFs, we introduce the total energy transfer balance model. Therein, the sum of energy transfer rates is considered along with its dependence upon the temperature: sign, magnitude, and variation of this parameter, permitting to afford a thorough interpretation of the observed behavior of the luminescent species of all materials presented here. The combination of novel theoretical and experimental studies presented herein to describe energy transfer processes in luminescent materials can pave the way towards the design of MOF-based chemical and physical sensors working in an optical range of interest for biomedical applications.
