“…The K SV values of 1 and 2 toward UA are obtained as 5.8 × 10 4 and 7.8 × 10 3 M –1 , respectively. The limits of detection (LODs) toward UA for 1 and 2 can be calculated to be 0.46 and 5.63 μM, based on the equation LOD = 3 s / K SV ( s is the standard deviation), which are similar to those of other reported luminescent sensors toward UA (Table S4). These results suggest that 1 and 2 both have excellent selectivity and sensitivity toward UA in water.…”

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.

“…Metal–organic frameworks (MOFs) are a kind of rapidly emerging porous materials self-assembled by metal ions or metal clusters and organic linkers through coordination interactions equipped with numerous fascinating virtues, such as porosity, structural diversity, and modifiability. − On the other hand, rare-earth ions, such as Sm 3+ , Nd 3+ , Er 3+ , and especially Eu 3+ and Tb 3+ , feature the characteristic fluorescent emission, millisecond-class fluorescent lifetime, high quantum yield, etc. − Integrating the advantages of MOFs and rare-earth ions, metal–organic frameworks fabricated with rare-earth ions (Ln-MOFs) have attracted a large amounts of attention toward their potential application in chemical sensors for various ions, − diverse antibiotics, − amino acids, − and different biomarkers. − …”

1-Hydroxypyrene (1-HP) is known as the end product of polycyclic aromatic hydrocarbons (PAHs). Monitoring the content of 1-hydroxypyrene in human urine or serum can help measure the degree of polycyclic aromatic hydrocarbon poisoning in the human body. Tryptophan (Trp), one of the eight essential amino acids, plays a vital role in human growth and development. Therefore, exploration of a promising sensor for instant and accurate recognition of 1-HP and Trp has a profound influence on human health. Herein, a threedimensional (3D) europium-centered metal−organic framework ([Eu-(H 2 O) 5 ] 0.33 [Eu(obdb)]•2DMF, Eu-MOF) with amazing air stability, acid−base stability, and thermal stability was constructed through the coordination interaction between Eu(III) ions and a V-typed semirigid ligand with two isophthalate groups (H 4 obdb, 4′,4‴-oxybis([1,1′biphenyl]-3,5-dicarboxylic acid)) under a solvothermal condition. As expected, Eu-MOF can recognize 1-HP and Trp in binary solutions of DMF-H 2 O based on a significantly luminescent turn-off effect with high quenching efficiencies (99.2% for 1-HP and 93.8% for Trp), charming quenching constants (2.15 × 10 4 M −1 for 1-HP and 4.88 × 10 4 M −1 for Trp), low limit of detection (1.10 μM for 1-HP and 0.73 μM for Trp), and satisfactory antijamming capability. In addition, for detection of 1-HP or Trp, the color change of Eu-MOF from red to blue is visible to the naked eye as the concentration of 1-HP or Trp increases under a 365 nm UV lamp. Moreover, except in DMF-H 2 O solutions, the sensing capacities of Eu-MOF toward 1-HP and Trp are proven to be comparable in HEPES buffer solution and real samples.
