Perfluorooctanesulfonic acid potassium salt (PFOS) residues in ecosystems over long periods are of increasing concern and require a selective stable optical probe for monitoring. Herein, two functional groups (-F -NH2) with opposite electronic modulation ability were introduced into Fe/Zn-BDC (denoted as Fe/Zn-BDC-F4 Fe/Zn-BDC-NH2, respectively) to tailor the coordination environment Fe metal center, further regulating nanozyme activity efficiently. Notably, peroxidase-like is related...
A novel ratiometric fluorescent method for the detection of copper ions (Cu2+) based on stimulus-responsive dual-ligand lanthanide luminol-Tb-GMP coordination polymer nanoparticle (CPNP) probe is reported in this study. The CPNPs are composed Tb3+ as center metal and ligand GMP together with cofactor luminol ligands bridging ligands. In presence Cu2+, fluorescence GMP-Tb response moiety dynamically quenched, while used reference remains constant. Hence, monitoring Cu2+ can be achieved by...
Luminol is introduced as a ligand for Tb<sup>3+</sup> which, combined with GMP, leads to sensor which more robust, sensitive, and efficient.
An arsenite assay based on the synergistic quenching effect of As(<sc>iii</sc>) and Ru(bpy)<sub>3</sub><sup>2+</sup> ECL Au–g-C<sub>3</sub>N<sub>4</sub> coupled with generation a new signal Ru(bpy)<sub>3</sub><sup>2+</sup>.
The photoluminescent (PL) properties of lanthanide metal-organic frameworks (Ln-MOFs) are intrinsically subtle to water molecules, which remains the major challenge that severely limits their applications as fluorescent probes in aqueous samples. Herein novel composite were prepared by growing Ln-MOFs (Tb-MOF, Eu-MOF, and Tb/Eu-MOF) on carboxylated porous graphene oxide (PGO-COOH). 3D thorny composites presented significantly longer lifetimes higher quantum yields than bare exhibited...
Carbon quantum dots (CQDs) are highly promising to be applied in light-emitting, chemosensing, and other cutting-edge domains. Herein, we successfully fabricate high-quality full-color CQDs under unprecedentedly low temperature pressure (85°C, 1.88 bar). Stable narrow fluorescent emissions ranging from blue green red light were realized by simple amine engineering, which further mixed into white-light with the absolute photoluminescent yield reaching 19.2%. The average mass of reached 69.0%....
Performing fast and accurate analysis of perchlorate in the environment is crucial for environmental public safety. In this work, a novel strategy modifying 4,4′-(3′,4′,5′,6′-tetrakis(4-(pyridin-4-yl)phenyl)-[1,1′:2′,1″-terpheny]-4,4″-diyl)dipyridine (TPD) with varied alkyl chains to realize bright monomer excimer emissions simultaneously fine-tune their emission properties was proposed. The thoroughly characterized via regulating concentration luminophore length chain. It found that could...
A novel method for highly selective recognition of UO22+ is proposed based on a [Eu(pyridine-2,5-dicarboxylic acid N-oxide)] (Eu-PDA) metal-organic framework. Benefiting from the unique chemical structure Eu-PDA, energy transfer PDA to was enabled, resulting in up-regulated fluorescence UO22+. The Eu-PDA probe showed excellent specificity over numerous interfering species, as intrinsic emissions were triggered.
Accurate determination of Ag+ released by silver nanoparticles (AgNPs) is vital for elucidating the environmental behaviors and defining exposure risks nanosilver. However, this remains challenging due to limitations in...

Uranyl ions (UO22+) are recognized as important indicators for monitoring sudden nuclear accidents. However, the interferences coexisting in complicated environmental matrices impart serious constraints on reliability of current on-site methods. Herein, a novel ratiometric method highly sensitive and selective detection UO22+ is reported based [Eu(diaminoterephthalic acid)] (Eu-DATP) metal–organic framework. Benefiting from unique chemical structure Eu-DATP, energy transfer DATP to was...
Herein, a new strategy to increase the sensitivity of lanthanide metal-organic framework (Ln-MOF) UO22+ was proposed by using polymeric ligands. By utilizing [Tb(1,3,5-benzenetrisbenzoate)]n (Tb-TBT) MOF as host, preloaded 2-vinyl terephthalic acid (VTP) polymerized in situ, which produced novel fluorescent composite denoted PVTP⊂Tb-TBT. Benefiting from coordination PVTP Tb nodes, chains performed both molecular scaffolds that improved water stability and additional antennae sensitized...
