The misuse of organic pollutants such as nitrofuran antibiotics (NFAs) and 2,6-dichloro-4-nitroaniline (DCN) has become a hot topic global concern, developing rapid, efficient, accurate techniques for detecting NFAs pesticides in water is major challenge. Here, we designed novel lead-based anion 2D metal-organic framework (MOF){[(CH3)2NH2]2[Pb(TCBPE)(H2O)2]}n (F3) with interlocking structures, which TCBPE stands 1,1,2,2-tetra(4-carboxylbiphenyl)ethylene. Powder X-ray diffraction thermogravimetric analysis revealed that F3 excellent chemical solvent stability. It worth noting grinding discoloration effect. solvent-protected approach achieved F3B high quantum yield (QY = 73.77%) blue fluorescence, while the direct method produced F3Y 37.27%) yellow-green fluorescence. Importantly, can detect rapidly sensitively remaining unaffected by other antibiotics. identify DCN quickly selectively unchanged pesticides. demonstrated selectivity rapid response to at limit detection (LOD) low 0.26 μM, indicated responded an LOD 0.14 μM. was successfully applied actual samples fish tanks ponds well pesticide soil samples. recovery rates were 97.0-105.15% 102.2-106.48%, relative standard deviations 0.63-1.45% 0.29-1.69%, respectively. In addition, be made into fluorescent test papers visual DCN, Combined experiments density functional theory calculations, mechanism fluorescence quenching MOFs target analytes also revealed.

Conjugated Aggregation-Induced Fluorescent Materials for Biofluorescent Probes: A Review

Biosensors, Год журнала: 2023, Номер 13(2), С. 159 - 159

Опубликована: Янв. 19, 2023

The common fluorescent conjugated materials present weak or quenching luminescent phenomena in the solid aggregate state (ACQ), which limits their applications medicine and biology. In last two decades, certain materials, named aggregation-induced emission (AIE) have exhibited strong properties state, can overcome ACQ phenomenon. Due to intrinsic properties, AIE been successfully used biolabeling, where they not only detect species of ions concentrations organisms, but also monitor organisms' physiological activity. addition, these kinds often non-biological toxicity. Thus, become some most popular biofluorescent probe are attracting more attention. This field is still its early infancy, several open challenges urgently need be addressed, such as materials' biocompatibility, metabolism, so on. Designing a high-performance material for probes challenging. this review, based on molecular design concept, various with functional groups introduced, including tetrastyrene distilbene anthracene triphenylamine hexaphenylsilole materials. according system strategy, donor-acceptor (D-A) hydrogen-bonding reviewed. Finally, concept potential evolution trends discussed. final goal outline theoretical scaffold that at same time further development AIE-based probes.
