WebNov 20, 2024 · Abstract. The ditopic ligands 2,6-dicarboxy-9,10-anthraquinone and 1,4-dicarboxy-9,10-anthraquinone were used to synthesize two new UiO-type metal-organic frameworks (MOFs; namely, 2,6-Zr-AQ-MOF and 1,4-Zr-AQ-MOF, respectively). The Pourbaix diagrams (E vs pH) of the MOFs and their ligands were constructed using … WebHomonuclear ditopic crystalline 2 : 1 (Na +: ligand) complexes (2a–4a, 2b–4b) of the ligands with NaSCN and NaClO 4 have been prepared. The NaClO 4 complexes of 3 and 4 (3b and 4b) form heteronuclear tritopic crystalline complexes with Ni 2+ cations of stoichiometry 2 : 1 : 1 (Na +: Ni 2+: ligand).
