Its content in organisms can serve as signaling molecules to directly or indirectly detect certain diseases. Therefore, based on the Michael addition mechanism, five flavonoid fluorescent probes HFL1-5 were designed and synthesized to detect cysteine. Through specific descriptions of IR,1H NMR and HRMS experiments, the recognition mechanism of cysteine by HFL was studied, demonstrating that HFL1-5 could generate flavonol derivatives with strong fluorescence emission through addition-cyclization-removal. The probes were evaluated for large Stokes shift, sensitivity, stability, specificity and cytotoxicity. Finally, the best performing HFL5 was selected for cell imaging experiments and successfully applied to the imaging of endogenous and exogenous cysteine in L929 cells. This study indicates that HFL has great potential for application in detecting cysteine.

Their unique ability to convert low-energy infrared light into high-energy visible or ultraviolet (UV) photons unlocks untapped resources in the solar spectrum and allows for deeper tissue penetration in biological imaging. By bridging the gap between recent advancements and remaining hurdles, we aim to inspire further research and accelerate the translation of these materials into practical and impactful applications for both energy and healthcare. This review delves into the recent trends propelling these materials forward. We explore advancements in UC efficiency through optimized material design, novel synthesis routes, and synergistic integration with existing technologies. In the domain of PVs, we shed light on strategies utilizing UC to address spectral mismatch and enhance light harvesting, paving the way for higher power conversion efficiencies. For biological applications, we illuminate the development of biocompatible and targeted UC probes, enabling deep tissue penetration, multimodality imaging, and theranostic potential. We critically analyze the current limitations and future directions of these materials, highlighting the challenges of toxicity, quenching, and scalability that remain to be tackled.

To address the limitations related to free curcumin (CUR), the present study focuses on the synthesis of curcumin-loaded poly lactic-co-glycolic acid nanoparticles (CUR NPs). The single emulsion solvent evaporation technique was used to synthesize CUR NPs with an average size of 187 nm and a zeta potential of -13.3 mV. Photophysical properties, drug loading efficiency, and drug release profile of synthesized CUR NPs were studied. Confocal fluorescence imaging was employed to study the cellular uptake of both formulations of CUR. The In-vitro investigation was conducted using BT-474 human breast cancer cells to evaluate the dark and phototoxic effect of both variants of curcumin (free CUR and CUR NPs). The cytotoxicity was quantified through half-maximal inhibitory concentration (IC50) obtained after conducting in-vitro dark and phototoxic experiments. The study revealed that CUR NPs showed better cytotoxic responses compared to the free CUR. During the phototoxic study, CUR NPs exhibit improved efficacy in the presence of light.

The performances of these sensitizers in dye-sensitized solar cells (DSSCs) were also studied.

The photophysical features of the sensitizers were evaluated via UV-Vis spectroscopy, revealing broad absorption in the visible range with λmax at 468 nm (MA-1) and 478 nm (MA-2) and corresponding molar extinction coefficients of 3.76 × 10⁴ M⁻¹cm⁻¹ and 5.34 × 10⁴ M⁻¹cm⁻¹, respectively. Electrochemical analysis showed favorable ground state oxidation potentials (GSOP) and excited state oxidation potentials (ESOP) for both dyes, with optical band gaps of 2.44 eV (MA-1) and 2.28 eV (MA-2). These values indicate efficient electron injection into the TiO2 conduction band and thermodynamic feasibility for dye regeneration. Co-sensitization using the benchmark N3 dye significantly enhanced the photovoltaic performance.

This superior performance can be attributed to the synergistic interactions between the dyes, broader spectral coverage, and improved charge separation dynamics.

Fluorescent probes based on the luminescence intensity of one transition is not efficient for probing BTEX. In this work, we have synthesized a luminescent RhB@MOF sensor array to realize the probing of different BETX by excellent fingerprint correlation between the BTEX and emission peak-height ratio of ligand to dye moieties. Three kinds of RhB@MOF were synthesized simultaneously by varying concentrations of Rhodamine B (RhB) in the solvothermal reaction of (E)-4-(2-carboxyvinyl)benzoic acid (H2L) and Cd(NO3)2·4H2O (RhB@MOF1, RhB@MOF2, RhB@MOF3). These sensors exhibited two characteristic emission peaks at 430 nm for the host CdMOF and 570 nm for guest RhB, and the emission peak height ratio I430/I570 were constant for each RhB@MOF. Upon reaction with BTEX, due to gap-gap reaction between ligand and different BETX as well as the different swelling effect of BTEX on RhB, the two emission peaks height ratio of three kinds of RhB@MOF showed specific change to different BTEX. The sensor array exhibited a unique pattern of fluorescence variations of BTEX. Principal component analysis (PCA) was applied and achieved complete separation of BTEX. Linear discriminant analysis (LDA) was then applied to discriminate between individual, binary, ternary, and quaternary mixtures of BTEX, resulting in a 100% accuracy rate. Further study also indicated that concentration gradients did not affect the clustering outcomes of BTEX. Compared to traditional methods, the developed fluorescent sensor array offered a more efficient and economical strategy for the identification of BTEX.","PeriodicalId":15800,"journal":{"name":"Journal of Fluorescence","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143567082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results emphasize the importance of substituent choice and positioning in determining dye spectral profiles. Specifically, placing an electron-withdrawing (EW) substituent at the 4-position of the coumarin ring results in longer emission wavelengths compared to substitution at the 3-position, while disubstitution at both the 3- and 4-positions provides a balance between emission wavelength and intensity. Introducing a julolidine group at the 7-position leads to red-shifted emissions and larger Stokes shifts, although this comes at the cost of reduced fluorescence intensity relative to N, N-diethylamino-substituted analogues. Notably, combining -COOH or -CN groups at the 3, 4-positions with either N, N-diethylamino or julolidine group at the 7-position offers a promising approach for tailored fluorescent dyes for optoelectronics and biological imaging.
