N2 - Three new anionic three-dimensional metal-organic frameworks based on heterocyclic polycarboxylate ligands have been synthesized: (H2NMe2)3[Zn2{NaZn2}(dabco)2(tdc)6]·4.5DMF·H2O (1, CCDC 2527083), (H2NMe2)[NaZn(fdc)2] (2, CCDC 2527084), (H2NMe2)[CdLi(btdc)2] (3, CCDC 2527085), where tdc2- = 2,5-thiophenedicarboxylate, dabco = 1,4-diazabicyclo[2.2.2]octane, DMF = N,N-dimethylformamide, fdc2- = 2,5-furanedicarboxylate, btdc2- = 2,2′-bithiophene-5,5′-dicarboxylate. The structure of the compounds has been established by single crystal X-ray diffraction analysis; the chemical and phase purity of compounds 2 and 3 has been proved by elemental, thermogravimetric and powder X-ray diffraction analyses and IR spectroscopy. The luminescence excitation and emission spectra of the solid phases 2 and 3 have been recorded, and the quantum yields have been obtained. The influence of mono-, di- and trivalent metal cations on the luminescence intensity of the suspensions of the MOF 3 has been investigated, and the luminescence response of the MOF suspensions to the presence of Co(II) and Ni(II) has been revealed and studied quantitatively.
