“…Since first reported in 2002, MOFs fluorescent probes have mushroomed . Many probes have been used to identify ions, small organic molecules, biomacromolecules, and nitroaromatic explosives et al . Among numerous LMOFs, uranyl fluorescence MOFs have the following characteristics compared with other LMOFs: (1) The fluorescence lifetime is long, which is benefit to time resolution.…”

A new coordination polymer (H2bpy)0.5⋅[(UO2)1.5(ipa)2(H2O)] (1) (H2ipa=isophthalic acid, bpy=4,4′‐bipyridine) was synthesized by hydrothermal condition. It was characterized by IR spectroscopy, elemental analysis, TG‐DTA analysis, and powder X‐ray diffraction. Analysis of single‐crystal X‐ray diffraction results showed that the title compound exhibited a double chain bridged by the different uranyl ions and ipa2− ligands. Through the hydrogen bond interactions and π⋅⋅⋅π stacking interactions, the double chains were assembled into the three‐dimensional supramolecular framework. Furthermore, the compound can be used as a promising bifunctional luminescence sensor for detecting and identifying Fe3+ and tetracycline hydrochloride antibiotic molecules with high selectivity and sensitivity in aqueous solutions. Moreover, the luminescent sensing mechanisms for different analytes were proposed. Moreover, the electronic properties of title compound were explored by density functional theory (DFT) calculations. The sensor system has been successfully applied for the detection of Fe3+ and tetracycline hydrochloride with high recovery percentages and low relative standard deviation in real river water samples.

“…The energy competition process relies on overlap of the absorption bands in both analytes and ligands . The high degree of absorption band overlap leading to low energy transfer efficiency from the ligand to the lanthanide . As shown in Figure S13, the ultraviolet visible absorption bands of ligands and DA are largely overlapped at 200–300 nm.…”

Dopamine (DA), which is a neurotransmitter of the nervous system and helps cell deliver pulse signals in the human body, is detected by a luminescent Tb‐functionalized metal‐organic framework (1a) sensor. The fluorescence quenching of as‐synthesized 1a in the presence of dopamine is owing to the energy competition effect of emission light as well as the interaction between 1a and DA. The sensor also displays outstanding performances, such as excellent sensitivity, fast response, good reusability, a wide linear detection range and lower detection limits. The sensor was also exhibited to be highly selective for DA in the presence of the main coexisting species. Significantly, the 1a sensor was able to detect DA in real human serum samples and DA portable test strips were also developed. Hence, the probe has promising potential to be a useful tool for point‐of‐care diagnosis of Parkinson's disease.

“…Among a wide variety of applications of MOF materials, the luminescent metal−organic frameworks (LMOFs) have recently attracted considerable interests, because of their superior photophysical properties, which can realize guest species recognition by readable luminescent enhancement or quenching effect . Nowadays, considering the novelty of this field in MOFs, more efforts have been devoted to developing new LMOF materials in sensing of heavy metal ions, anions/cations, oxygen, volatile organic compounds (VOCs), and nitroaromatic explosives, etc . Nevertheless, it is still a big challenge and meaningful research topic to develop new LMOFs with the advantages including sensitivity, selectivity, convenience and reusability to detect toxic anions (such as Cr 2 O 7 2− , MnO 4 − etc.)…”

Three metal‐organic frameworks {[Cd(L)(glu)]⋅3 H2O}∞ (1), {[Cd2(L)2(adi)2]⋅5 H2O}∞ (2) and {[Cd(L)(sub)]⋅3 H2O⋅DMA }∞ (3) (L=pyridine‐3,5‐bis(5‐azabenzimidazole), H2glu=glutaric acid, H2adi=adipic acid and H2sub=suberic acid) were obtained under solvothermal conditions. Complex 1 shows a 2D (4,4) network constructing of Cd2‐glu and Cd‐L chains. Complex 2 presents a 2‐fold interpenetrating 3D framework with pcu topology. Complex 3 is a 3D framework with cds topology. Three complexes with versatile structures were obtained by changing aliphatic dicarboxylate ligands with different lengths based on a N‐rich ligand. Moreover, the fluorescence measurements indicate that complex 1 is a good multifunctional chemosensor for the detection of Cr2O72− and MnO4− anions by fluorescence quenching effect, and ethylenediamine by fluorescence enhancement effect, with detection limits of 1.196 ppm, 0.551 ppm and 64.572 ppm, respectively. Both complexes 2 and 3 can selectively sense Cr2O72− anion with detection limits of 1.126 ppm for 2 and 0.831 ppm for 3 by a fluorescence quenching effect.
