“…Among diverse organic fluorophores, rhodamines are noted for their high fluorescence quantum yield, large absorption coefficient and wide wavelength range. In recent years rhodamine-based sensors have been widely applied to recognize metal ions [ 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 ]. However, most of these sensors are insoluble in water due to their hydrophobicity.…”

A fluorescent and colorimetric poly (acrylamide)-based copolymer probe P(AAm-co-RBNCH) has been designed via free radical polymerization of a commercial acrylamide monomer with a rhodamine-functionalized monomer RBNCH. Metal ion selectivity of RBNCH was investigated by fluorescence and colorimetric spectrophotometry. Upon addition of Fe3+, a visual color change from colorless to red and a large fluorescence enhancement were observed for the ring-opening of the rhodamine spirolactam mechanism. The monomer gives a sensitive method for quantitatively detecting Fe3+ in the linear range of 100–200 μM, with a limit of detection as low as 27 nM and exhibiting high selectivity for Fe3+ over 12 other metal ions. The hydrogel sensor was characterized by FTIR, and the effects of RBNCH amount on gel content and swelling properties were explored. According to the recipe of 1.0 mol% RBNCH to the total monomers, the fabricated hydrogel sensor displayed a good swelling property and reversibility performance and has potential for application in the imaging of Fe3+ level in industrial wastewater.

“…A uorescence probe is a simple, fast, and sensitive way of detecting copper ions compared with traditional methods such as electrochemistry, 16 spectrophotometry, 17 voltammetry, 18 and atomic absorption spectroscopy. 19 Many sensitive uorescence probes for Cu 2+ have been reported, such as ferrocenyl, 20 benzimidazole, 21 benzothiazole, 22,23 pyrene, 24,25 BODIPY, 26,27 rhodamine, [28][29][30][31] etc. Pyrimidine is a typical nitrogen heterocyclic compound and has many structure sites that can be modied.…”

“…Fluorescent probes have always played important roles in the detection of different biomolecules because of their significant features such as spatiotemporal resolution in living systems (10), high sensitivity, relatively simple analysis protocols (11)(12)(13) and low cost. As a result, fluorescent sensors have become a hot topic in the detection of different metal ions (14)(15)(16), cations (17), anions (18)(19)(20), and biomolecules (21)(22)(23).…”

The simultaneous discrimination of cysteine (Cys), homocysteine (Hcy) and glutathione (GSH) is of great importance due to their roles in biology and close link to many diseases, especially via the development of a far-red fluorescent probe that could be used for rapid, selective, and sensitive detection of all three. Herein, we report the characterization of a far-red fluorescent probe with turn-on fluorescence properties and visible color changes that could be used for the detection of cysteine and homocysteine over glutathione. In this study we found that the sensor could discriminate cysteine and homocysteine over glutathione within 20 min. Function of this probe was based on the conjugate addition-cyclization reaction and showed a low detection limit to cysteine and homocysteine. Upon the addition of cysteine and homocysteine, the absorption band at 592 nm rose gradually and fluorescence was detected at 645 nm. The color changed from colorless to blue and fluorescence changed from absent to strong red fluorescence, which could be differentiated by the naked eye. All these unique features make this probe particularly potentially favorable for use in cysteine/homocysteine sensing and bioimaging applications. Copyright © 2016 John Wiley & Sons, Ltd.
