Two 3D solvent-stable zinc(ii)-lanthanide(iii) heterometallic metal-organic frameworks (MOFs) {[(CH3)2NH2]2[Zn2Ln2(FDA)6(DMF)2]·2DMF}n [Ln = Eu (Zn-Eu) and Tb (Zn-Tb); H2FDA furan-2,5-dicarboxylic acid] based on Zn2Ln2(COO)10 tetrametallic clusters acid have been successfully synthesized. These MOFs can serve as luminescent sensors for the fast response highly selective detection of aniline via luminescence quenching. More importantly, a linear correlation is observed between their low concentration limits are 7.5 μmol L-1 Zn-Eu 5.2 Zn-Tb.
