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).

WebThe self-assembly of a new family of triple-stranded helicates with fascinating chiral characteristics from axially chiral 1,1′-biphenyl-type ligands are reported. The fine-tuning of chiral microenvironments within the well-defined complexes has enabled outstanding chiral discrimination properties, leading to highly enantio- and helix-sense ... WebJun 18, 2024 · Imidazole-based ditopic ligands bearing two chiral alkyl groups (L RR, L SS, and L RS) were synthesized.The ligands formed Pd 2 L 4 helicates with palladium ions (Pd 2+).Self-sorting occurred between L RR and L RS to form (Pd 2+) 2 (L RR) 4 and (Pd 2+) 2 (L RS) 4 homoligand assemblies, whereas mixing of L RR and L SS with Pd 2+ gave a … bleach and urine mix
