“…The emissions of CPs 1 and 2 are closer to those of the Mbimb or bbimb ligands, suggesting that the emissions of two CPs should mainly originate from the π*→ π and π*→ n transitions of the Mbimb or bbimb in the structure; 38,39 the slight shifts of their emissions suggest that they can also be affected by the 1,5-NDS ligand and the coordination of the ligands to Zn(II) centers. 40,41 The CIE color coordinates of the two CPs are (0.1619, 0.056) and (0.1729, 0.0889), respectively, which are both located in the blue region. The luminescence stability of two CPs in aqueous solution was also tested.…”

Two novel coordination polymers (CPs), [Zn2(μ-OH)2(μ-1,5-NDS-κ2 O:O′)(μ-Mbimb-κ2 N:N′)] n (1) and {[Zn(CH3COO-κ1 O)(μ-bbimb-κ2 N:N′)1.5](1,5-NDS)0.5} n (2), were synthesized by hydrothermal reaction of Zn(Ac)2·2H2O with 1,5-naphthalenedisulfonate (1,5-NDS2–), 1,4-bis(2-methyl-1H-imidazole-1-yl)butane (Mbimb), or 1,4-bis(1H-benzimidazol-1-yl)butane (bbimb). In the crystal structure of 1, the Zn(II) centers are connected by μ-OH– anions into an infinite –[Zn(OH)] n – chain, which is further linked by Mbimb and 1,5-NDS2– to form a 3D dia network. In 2, the Zn(II) centers are linked by bbimb ligands into a 2D (6,3) brick wall layer with Ac– as dangling arms threaded into the space of adjacent layers, resulting in a 2D → 3D polythreading structure. Luminescent studies reveal that both CPs have excellent luminescence stability and can selectively detect uric acid (UA), MnO4 –, and Cr(VI) oxo-anions in aqueous solutions with high quenching efficiency. The limits of detection toward UA, MnO4 –, CrO4 2–, and Cr2O7 2– are 0.46, 4.33, 5.50, and 1.60 μM for CP 1 and 5.63, 2.84, 7.60, and 2.90 μM for CP 2, respectively. Moreover, the two CPs can also serve as luminescence sensors to detect UA in serum and MnO4 – and Cr(VI) oxo-anions in tap water. The luminescent films of the CPs were also prepared for visual detection of UA, MnO4 –, CrO4 2–, and Cr2O7 2– with the naked eye.

Two Co‐based supramolecular isomers were synthesized from a fluorinated carboxylic acid ligand under hydrothermal conditions at varying temperatures. Both exhibited similar one‐dimensional chain structures while different bending connections of the aromatic rings led to different supramolecular structures, namely CoCP‐1 and CoCP‐2, respectively. The structural differences of two isomers resulted in discrepant performance with regards to luminescence sensing and catalysis. CoCP‐1 demonstrated more significant luminescence quenching activity toward biomarkers 2,6‐dipyridinoic acid (DPA) and high vanilloid acid (HVA), which could be distinguished in the presence of Eu3+. The limit of detection (LOD) was found to be as low as 3.4 and 1.3 μM, respectively. The recovery rate of for HVA and DPA was within the range of 89.6‐101.2% and 99.7‐117.9% in simulated urine and serum, respectively, indicating potential reliability in monitoring these two analytes in real samples. Notably, CoCP‐2 exhibited catalytic activity for the oxidation of thioethers to sulfoxides. Our finding here suggests that the coordination conformation of the ligands within supramolecular isomers plays a pivotal role in determining the structure and luminescence sensing/catalysis performance.
