“…Various derivatives of this polycyclic aromatic hydrocarbon have displayed strong and distinct excimer emission with high fluorescence quantum yield. Though the fluorophore occasionally experiences quenching due to aggregation in solid or concentrated form, pyrene derivatives are used extensively in fluorescent probes, food colorants, OLEDs, biosensors, biomarkers, corrosion inhibitors, printing inks, chemosensors, colorimetric sensors (Kathiravan et al 2014;Domeño et al 2017;Shen et al 2019;Srinivasan et al 2021;Wang 2021), electroluminescent devices, paints, optoelectronics, (Gowri et al 2020;Jeyasingh et al 2021;Kr et al 2021;Uzun 2021;Yao et al 2021), and anti-counterfeiting (Maeda et al 2001;Homa et al 2017;Mohamed et al 2020;Boonnab et al 2021). Although various colorants are available, very few inks, such as bio-ink and tattoo inks, have been developed utilizing pyrene, primarily for inkjet and 3D printing.…”

Fluorescence-based materials that are affordable and easy to use for commercial anti-counterfeiting applications are in high demand. While exploring new fluorescent pigments, a pyrene-naphthalimide Schiff base, 5-hydroxy-2-((pyren-1-ylmethylene)amino)-1H-benzo[de]isoquinoline-1,3(2H)-dione (NHPY) with yellow fluorescence under UV light was synthesized. An eco-friendly flexographic ink prepared with NHPY as the pigment was coated on a UV dull paper and further printed on security paper as well as packaging papers and boards. When exposed to UV light, the printed samples showed yellow fluorescence. The light fastness, gloss, colorimetric results, and abrasion resistance of the printed samples proved that NHPY is a suitable fluorescent pigment for security printing applications.

“…Currently, technical means have been developed for the analytical detection of Fe 3+ , mainly fluorescent sensors, atomic absorption (AAS), inductively coupled plasma mass spectrometry (ICP-MS), potentiometric solvation analysis (PSA), X-ray fluorescence spectrometry (XRF), and radioisotope labeling [ 23 , 24 , 25 ]. Among them, the fluorescence probe detection technique has recently become one of the most important means to detect the Fe 3+ content in organisms or the environment because of its advantages such as high selectivity, simple operation, high sensitivity, visualization, and non-damage to the detection sample [ 26 , 27 , 28 , 29 ].…”

In this paper, a molybdenum disulfide fluorescent probe with an Fe3+ fluorescent system was first synthesized by the hydrothermal method for the detection of iron ion concentration in oral solution of protein succinate. It was characterized by infrared, fluorescence, X-ray photoelectron spectroscopy, scanning electron microscopy, and transmission electron microscopy. The probes were found to have good stability, photobleaching, and storage stability. The effects of dilution, pH, reaction time, and iron ion concentration on the fluorescent system were also investigated. The relative fluorescence intensity [(I0 − I)/I0] showed a good linear relationship with the iron ion concentration in the range of 0–50 μM, with the linear equation [(I0 − I)/I0] = 0.0148[Fe3+] + 0.0833 (r2 = 0.9943, n = 11) and the detection limit of 2.43 μM. The reaction mechanism was also explored, as well as its ion selectivity, reversibility, accuracy, precision, and concentration of Fe ions in the actual sample. It was found that the probe can selectively detect Fe ions with a certain degree of reversibility, accuracy, precision, and ideal recovery, and it can be used for the determination of Fe3+ in proteosuccinic acid oral solution.

Preparation of non-conjugated polymers with longwavelength emission and high quantum yield (QY) is still ahuge challenge.Herein, we report the first example of linear non-conjugated polyester exhibiting yellow-green clusteroluminescence (CL) and ah igh QY of 38 %. We discovered that the polyester P3 with balanced flexibility and rigidity showed the longest CL wavelength and highest QY.S ystematically photophysical characterization unravel the key role of ester cluster in the CL and the cluster formation via the aggregate of ester units was visualized. Moreover,P 3w as demonstrated to be ah ighly selective,q uick-responsive (ca. 1.2 min) and sensitive detector (detection limit is 0.78 mM) for irons owing to the fast disassociation of clusters by irons.T his work not only gains further mechanistic insight into CL but also provides an ew strategy to design high-efficiency and longwavelength CL, meanwhile,enlightens the glorious application prospect of luminescent polyester.
