Water Stable Heterometallic Zn–Tb Coordination Polymer for Rapid Detection of the Ultraviolet Filter Benzophenone

Abstract

Benzophenone (BP) is an ultraviolet filter (UVF) widely used in personal care products such as sunscreens and cosmetics. Excessive exposure to BP-type UVFs is a potential threat to human’s health because of their endocrine-disrupting activity. Water stability of lanthanide compounds is crucial when they serve as luminescent sensors because of the practicality and recyclability. In this study, a water-stable luminescent Zn–Tb heterometallic coordination polymer was rationally designed and synthesized for rapid detection of BP. This material showed a high quenching effect, excellent selectivity, and fast response toward BP.

A Europium–Organic Framework Sensing Material for 2-Aminoacetophenone, a Bacterial Biomarker in Water

“…Lanthanide metal–organic frameworks (Ln-MOFs) constructed by lanthanide nodes and organic linkers via coordination bonds are promising sensing materials for not only their permanent porosities and structural tunabilities , but also excellent photoluminescence based on an “antenna effect” − with rapid and efficient sensing performance because the photoluminescence of Ln-MOFs can be fine-tuned by the host–guest interaction through rational structure and energy-level matching. − To date, well-designed luminescent Ln-MOFs have successfully been studied for the detection of gases, cations, anions, volatile organic compounds and persistent organic pollutants, , chiral molecules, biomakers, biomolecules, and so on. However, to the best of our knowledge, the application of Ln-MOFs for the detection of PA or its biomarker has not been reported.…”

A water-stable terbium metal–organic framework as a highly sensitive fluorescent sensor for nitrite

“…4, the S-V plots show a linear relationship at the completed concentration range, which is different from that of the concentration controlled by a self-absorption process. [51][52][53][54][55] The luminescence lifetimes of Tb-MOF were measured at 544 nm with different concentrations of the nitrite ions (Fig. S15 and Table S4 †).…”

“…Among these methods, the fluorescence sensing technology include the advantages of rapid response, low cost and easy-operation. 46 In this study, based on the fluorescence sensing mechanism and our experience on MOF-based sensing materials, [47][48][49][50][51][52][53][54][55][56]…”

Chiral Luminescent Sensor Eu-BTB@d-Carnitine Applied in the Highly Effective Ratiometric Sensing of Curing Drugs and Biomarkers for Diabetes and Hypertension

“…In these fields, enantiomers usually exhibit different properties under certain circumstances; specific isomers can cause fatal effects on living cells. As a new type of porous material, metal–organic frameworks (MOFs) show robust application in separation, gas storage, catalysis, ion exchange, fluorescence, drug storage, and release due to their structural diversity, adjustable pore size, and large specific surface area. − Compared with other luminescent materials such as Au nanoparticles and quantum dots, MOFs can adsorb target molecules into pores, thereby achieving local enrichment and further realizing functional recognition. − As a member of the MOF family, chiral MOFs and MOF-based chiral hybrid materials inherit the above-mentioned advantages of MOFs, and they also have good chirality selection toward special enantiomers. − For example, Zaworotko and his co-workers changed the shape and size of the pores to construct a dynamic chiral MOF based on 1,2-dichlorobenzene, CMOM-3S. CMOM-3S can be used as a powerful tool for chiral purification and enantiomer identification.…”
