摘要：
Compounds Rh6G-1 and RhB-2 with a novel receptor composed of tri-oxygen atoms of amide groups were designed and synthesized as new reversible fluorescent sensors for Fe 3+ . The prominent features of the novel sensor Rh6G-1 include a large fluorescence turn-on response in essentially pure water at room temperature, high sensitivity, high selectivity, a limit of detection, cell membrane permeability, and low cytotoxicity. These desirable attributes enable us to successfully employ the new sensor Rh6G-1 for Fe 3+ bioimaging in living cells. © 2018 Jiaoliang Wang et al., published by De Gruyter.

摘要：
A near-infrared fluorescent probe NIR-Hg, for the detection of Hg2+ ion, has been synthesized directly by condensing Changsha dye with 4-Phenyl-3-thiosemicarbazide and the structure has fully characterized by 1HNMR, 13CNMR, and ESI-MS. The probe has been designed on the basis of the reaction that Hg2+ ion promotes thiosemicarbazide to oxazole in aqueous media and had been induced to produce turn-on fluorescence via an irreversible spirolactam ring-opening process. The probe NIR-Hg has exhibited fast response (1 min), high sensitivity with 44-fold fluorescence intensity enhancement under six equivalent amounts of Hg2+ added, high selectivity over other related metal ions and a low detection limit of 5.8 × 10-8 M in the phosphate buffer. The linear response range covers the concentration of Hg2+ from 5 × 10-7 to 5 × 10-6 M. In addition, the probe has good cell-membrane permeability, which is suitable for fluorescence imaging for Hg2+ in living cells and in vivo mice. © 2017 IOP Publishing Ltd.

摘要：
Mercury is one of the deadly toxic metals to humans. A new fluorescent probe CS-Hg for Hg<sup>2+</sup>has been designed and synthesized based on the Hg<sup>2+</sup>-promoted cyclization and the CS NIR platform. The probe upon interaction with different metal ions showed good sensitivity and high selectivity for Hg<sup>2+</sup>through fluorescence “turn-on”response in PBS buffer. Significantly, the probe CS-Hg is highly reactive to Hg<sup>2+</sup>with a very rapid response. Furthermore, we have demonstrated that the probe is applicable for Hg<sup>2+</sup>imaging in the living cells and in animals. ©2017 Elsevier B.V.

摘要：
A turn-on fluorescent probe Coumarin-SO2 based on a nucleophilic addition reaction was developed for the rapid detection of SO32- in aqueous media. The probe Coumarin-SO2 displays excellent water solubility, fast response, highly sensitivity and highly selectivity over other biological related species. More importantly, living cell imaging experiments indicate the feasibility of using the probe for the detection of SO32- in biological systems. Copyright (c) 2015 John Wiley & Sons, Ltd.

摘要：
A rhodamine-based fluorescence chemsensor bearing the 8-hydroxyquinoline unit is developed as a reversible turn-on chemosensor for Cu<sup>2+</sup>. It exhibits a highly sensitive fluorescent response toward Cu<sup>2+</sup> in aqueous media with an 80-fold fluorescence intensity enhancement under 10 equiv. of Cu<sup>2+</sup> added. This indicates that the synthesized chemosensor effectively avoided the fluorescence quenching for the paramagnetic nature of Cu<sup>2+</sup> via its strong binding capability toward Cu<sup>2+</sup>. The chemosensor Rh-Q exhibits a dynamic response range for Cu<sup>2+</sup> from 2 ×10<sup>-7</sup> to 5 ×10<sup>-5</sup> M, with a detection limit of 0.19 μM, and good selectivity for Cu<sup>2+</sup> over other heavy and transition metal (HTM) ions in Tris-HCl/EtOH (7:3, v/v, pH 7.4). In addition, the turn-on fluorescent change upon the addition of Cu<sup>2+</sup> is also applied in cell imaging. ©2012 Elsevier B.V. All rights reserved.

摘要：
A displacement method of detecting hydrogen sulfide in aqueous media based on complex L–Cu ensemble is developed. Once combined with Cu2+, complex L–Cu displayed high specificity for sulfide anion. Among the various anions, only sulfide anion induce the revival of fluoresecence of compound L, which is quenched by Cu2+, resulting in turn-on type sensing sulfide anion. Complex L–Cu exhibits a highly sensitive fluorescent response toward S2− by releasing compound L to give a remarkable change with 20-fold fluorescence intensity enhancement under 2 equivalent of S2− added in Tris–HCl/ DMF (20 mM, 6/4, v/v), and also exhibits a dynamic response range for S2− from 5×10−7 to 5×10−6 M, with a detection limit of 0.18 μM. In addition, the turn-on fluorescent change upon the addition of S2− is also applied in cell imaging.

摘要：
A new effective fluorescent sensor based on rhodamine was synthesized, which was induced by Cu<sup>2</sup> in aqueous media to produce turn-on fluorescence. The new sensor 1 exhibited good selectivity for Cu<sup>2</sup> over other heavy and transition metal (HTM) ions in H<inf>2</inf>O/CH <inf>3</inf>CN(7:3, v/v). Upon addition of Cu<sup>2</sup>, a remarkable color change from colorless to pink was easily observed by the naked eye, and the dramatic fluorescence turn-on was corroborated. Furthermore, kinetic assay indicates that sensor 1 could be used for real-time tracking of Cu<sup>2</sup> in cells and organisms. In addition, the turn-on fluorescent change upon the addition of Cu<sup>2</sup> was also applied in bioimaging. ©2012 Elsevier B.V. All rights reserved.

摘要：
A novel p-acetaminophen resin (named as GQ-1) was synthesized with chloromethylated polystyrene and p-acetaminophen. It can be used without any wetting process. The objective of this work was to study the adsorption performances for vanillin onto GQ-1 with two kinds of the hydrogen bond site of acetamino group and hydroxyl group. The results showed that the adsorption property of vanillin onto GQ-1 was superior to XAD-4, H103, NDA150, and NDA88. The adsorption capacity of vanillin onto GQ-1 is not greatly discrepant until the solution pH is higher than 5.31. The saturated adsorption quantity of vanillin was up to 141.32 mg/mL (wet resin) according to the dynamic adsorption and desorption experiments at 293 K. The resin could be regenerated by 7 BV ethanol. © 2011 Gu Qing Xiao.
