A new luminescent Zn(II)-based metal–organic framework (MOF), [Zn2(TPOM)(NDC)2]·3.5H2O (Zn-MOF; TPOM = tetrakis(4-pyridyloxymethylene)methane and H2ndc 2,6-naphthalenedicarboxylic acid), was successfully synthesized by a hydrothermal reaction. The MOF exhibits excellent luminescence emission, it can detect Fe(III) Cr(VI) ions with high selectivity, well antiinterference performance, short response time. In addition, Zn-MOF selected as parent coordination compound to encapsulate Eu3+ cations...
With the introduction of Eu3+ ions as secondary fluorescent signal reporter and sensing active sites, a dual-emission ratiometric sensor Eu3+@NiMOF (Eu3+ functional NiMOF) for hippuric acid (HA) detection in urine serum was fabricated via postsynthetic encapsulating strategy. Based on two emission signals at 441 nm (turn-on) 628 (turn-off), produced provided enhanced sensitivity, higher selectivity, 9.7 times lower limits (LOD) HA (2.38 μM, 0.42 μg·mL-1) than that pristine NiMOF. Considering...

Developing efficient and sensitive MOF-based luminescence sensors for bioactive molecule detection is of great significance remains a challenge. Benefiting from favorable chemical thermal stability, as well excellent performance, porous Zn(II)Ho(III) heterometallic-organic framework (ZnHoMOF) was selected here bifunctional sensor the early diagnosis toluene exposure biomarker hippuric acid (HA) through "turn-on" enhancing response daily monitoring NFT/NFZ antibiotics "turn-off" quenching...
By changing the ratio of reactants, two mononuclear Dy complexes, [Dy(phen)(acac)3] (1) and [Dy(phen)2(NO3)2(acac)]·H2O (2) have been synthesized structurally characterized. In 1, a atom bearing square-antiprism coordination geometry exhibits SMM behaviour, while compound 2 with bicapped-square-antiprism does not show such properties. The different magnetic behaviours seen in 1 are probably due to environment ligand field around Dy(III) ions. results proved important influence structural on...
Semiconductive metal–organic frameworks (MOFs) have attracted extraordinary research interest in recent years; however, electronic applications based on these emerging materials are still their infancy. Herein, we show that a lanthanide-based semiconductive MOF (SCU-12) can effectively convert X-ray photons to electrical current signals under continuous hard radiation. The MOF-based polycrystalline detection device presents promising sensitivity with the value of 23.8 μC Gyair–1 cm–2 80 kVp...

Using ratio of intensity at 416 614 nm, MOF could quantitatively determine concentration dry ethanol bioethanol with recoveries 91%...
A global international initiative, such as the Earth BioGenome Project (EBP), requires both agreement and coordination on standards to ensure that collective effort generates rapid progress toward its goals. To this end, EBP initiated five technical committees comprising volunteer members from genomics scientific community: Sample Collection Processing, Sequencing Assembly, Annotation, Analysis, IT Informatics. The current versions of resulting documents are available website, with...
The major advantage of laser lighting over white light-emitting-diode is the possibility to achieve ultra-high luminance. However, phosphors usually suffer laser-induced luminescence saturation, which limits peak luminance devices. aim present study develop LuAG:Ce/Al<sub>2</sub>O<sub>3</sub> composite ceramics (LACCs) with a high saturation threshold for high-luminance lighting. Owning rigid crystal structure, proper synthetic process, and optimized thermal design, LACCs possess small...
