Acidity and Cd fluorescent sensing and selective CO adsorption by a water-stable Eu-MOF
A new Eu-MOF was designed from an amino-functionalized ligand and Eu( iii ) ions under solvothermal conditions. It is a highly porous, water-stable, and luminescent material, exhibiting pH sensing in the acidic range of pH = 7-3 with selective detection for Cd 2+ by an enhanced fluorescence of ∼23-f...

(15/85) selectivity of 109.4 at 273 K and 1 atm. This performance was superior to that of most reported Ln-MOFs owing to its appropriate pore size, dipole-dipole interaction and donor-acceptor Lewis affinities.
A new luminescent Eu-MOF from an amino-group modified tetracarboxylic acid ligand was designed, which could perform as an efficient pH acidity and Cd
