Here, the synthesis by a soft solvothermal route of two novel isoreticular compounds based on in situ generated (by nucleophilic aromatic substitution) 2-hydroxi-5-(trifluoromethyl)pyrimidine (H1L) ligand and Zn(II) Cd(II) as metallic centers (with general formula [ML2]n labeled GR-MOF-30 for M = Zn GR-MOF-31 Cd) is reported, together with their detailed structural photoluminescent characterization. These metal–organic frameworks are first examples coordination constructed this ligand. Structures show remarkable intermolecular interactions, including C–F···π π···π stacking, which not only stabilize structure but also improve luminescent properties materials. DFT calculations were employed to unequivocally assign bands observed UV–vis solid-state spectroscopy. A photophysical study materials revealed that GR-MOF-31present fluorescence band maxima at 394 388 nm, respectively, phosphorescence emission lifetimes 500 48.1 ms 450 69.2 GR-MOF-31. Interestingly, photoluminescence compound hardly affected change temperature; meanwhile, shows transition from dominating fluorescent room temperature phosphorescent 25 K.

Lanthanide metal-organic frameworks combine the luminescent properties of rare earth elements with structural tunability molecular frameworks, making them ideal for multifunctional applications, such as luminescence sensing and gas separation. Herein, we report synthesis a red microporous Eu-MOF {[Eu2(H2O)L3]·3H2O}n using 1,2,5-thiadiazole-3,4-dicarboxylic acid (H2L) sole ligand. The H2L ligand features an effective antenna effect energy transfer rigidity, enabling formation robust framework. Detailed analysis revealed its highly ordered microporosity. exhibited excellent performance detecting nitrofuran antibiotics, including nitrofurantoin (NFN) nitrofurazone (NTZ), demonstrating high selectivity, low detection limits, short response time (both within 6 s). Furthermore, structure endowed it exceptional adsorption properties, methane-acetylene
