Tuning the luminescence of two 3d-4f metal-organic frameworks for the fast response and highly selective detection of aniline

Two 3D solvent-stable zinc(ii)-lanthanide(iii) heterometallic metal-organic frameworks (MOFs) {[(CH ) NH ] [Zn Ln (FDA) (DMF) ]·2DMF} [Ln = Eu (Zn-Eu) and Tb (Zn-Tb); H FDA = furan-2,5-dicarboxylic acid] based on Zn Ln (COO) tetrametallic clusters and furan-2,5-dicarboxylic acid have been successful...

Summary:Two 3D solvent-stable zinc(ii)-lanthanide(iii) heterometallic metal-organic frameworks (MOFs) {[(CH ) NH ] [Zn Ln (FDA) (DMF) ]·2DMF} [Ln = Eu (Zn-Eu) and Tb (Zn-Tb); H FDA = furan-2,5-dicarboxylic acid] based on Zn Ln (COO) tetrametallic clusters and furan-2,5-dicarboxylic acid have been successfully synthesized. These MOFs can serve as luminescent sensors for the fast response and highly selective detection of aniline via luminescence quenching. More importantly, a linear correlation is observed between their luminescence and the low concentration of aniline and the detection limits of aniline are 7.5 μmol L for Zn-Eu and 5.2 μmol L for Zn-Tb.
