“…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.

“…There are numerous kinds of cell imaging techniques that are available but fluorescence imaging has proved to be more trustworthy due to its sensitivity toward live cells. , Till now, various kinds of luminescent materials like quantum dots, nanosheets, and metal nanoclusters have been used for cell imaging. − But nowadays, MOFs are used as unique probes in cell imaging due to their luminescence performance and quenching and turn-on properties . Over the past few years, several research works on the bioimaging studies of MOF-based materials have been reported. ,− …”

A two-dimensional copper-based metal–organic framework, [Cu(C23H14O6)(C10H8N2)2]·H2O·DMSO, 1, was synthesized using pamoic acid (C23H16O6) and 4,4′-bipyridine (C10H8N2) as an organic ligand and Cu(II) as a metal ion. Single-crystal structure X-ray diffraction studies of the as-synthesized compound showed a two- dimensional structure with free hydroxyl groups. Upon excitation at 370 nm, the aqueous dispersion of [Cu(C23H14O6)(C10H8N2)2]·H2O·DMSO, 1, showed emission centered at 525 nm resulting from the intraligand energy transfer. Fluorescence microscopic experiments using a human epithelioid cervix carcinoma HeLa cell line were carried out, clearly showing that our compound selectively stained the cellular nucleus. To utilize the porous nature of [Cu(C23H14O6)(C10H8N2)2]·H2O·DMSO, 1, its dye sorption behavior in aqueous solution was determined, and a high affinity for methylene blue (MB) dye was confirmed. Our synthesized compound sorbed 88% MB dye with an initial concentration of 32 mg L–1, and its sorption capacity for MB was found to be 29.79 mg g–1. The possible mechanism of the dye sorption behavior was discussed in terms of the size and charge of dye molecules with respect to molecular-level interactions between the framework and the dye molecules.

The self‐assembly of the π‐conjugated 1,4‐di(1H‐imidazol‐1‐yl)benzene (dib) and 4,4′‐di(1H‐imidazol‐1‐yl)‐1,1′‐biphenyl (dibp) ligands together with 4′‐(3,4‐ dicarboxylphenyloxy)‐4‐biphenylcarboxylic acid (H3L) reacts with metal Zn (II) salts to construct two new coordination polymers (CPs), namely [Zn (dib)(HL)(H2O)] (1) and [Zn (dibp)(HL)] (2). Fluorescence measurements reveal that 1 and 2 could display a highly sensitive fluorescence response toward Hg2+ and nitrofurazone (NFZ). Fluorescence investigations suggest that 1 and 2 are promising multi‐responsive sensing materials for detecting Hg2+ and NFZ through fluorescence quenching (turn‐off). The limits of detection toward Hg2+ ions are 0.221 μM and 0.124 μM, while the limits of detection toward NFZ are 0.757 μM and 0.960 for 1 and 2, respectively. Interestingly, these Hg2+ and NFZ selective sensing processes can even be completed by the reusable CPs detected by the naked eyes. Hirshfeld surfaces and fingerprint plots are extensively used to investigate intermolecular interactions, which play a crucial role in creating diverse supramolecular designs that can be compared.
