Rhodamine based colorimetric and fluorescent probe for recognition of nucleoside polyphosphates through multi-hydrogen bond

A novelty rhodamine B based chemosensor containing 2-amino-7-methyl-1, 8-naphthyridine moiety was designed and synthesized for colorimetric and fluorescent response on corresponding nucleoside polyphosphates through multi-hydrogen bond interaction in aque

Molecular engineering and biomedical applications of ultra-sensitive fluorescent probe for Ag+

A series of probes KJ-x (x = 1?3) with carbon chains of different lengths based on the matrix of rhodamine B were engineered to detect Ag+ in aqueous solution in this work. Among them, KJ-1 is selected as the best option after in vitro investigation in view of its most sensitive and rapid response to Ag+, whose possible sensing mechanism is studied by experimental investigation and theoretical calculation. To identify the practical application of the probe, the detection of Ag+ in nonantibiotic fungicide Silver&Health and differentiation between normal hepatocytes and hepatoma cells using confocal imaging was conducted.

Signalling probes appended with two rhodamine derivatives: Inter-component preferences, Fe(III)-ion selective fluorescence responses and bio-imaging in plant species

The photophysical investigation of two amino-alkyl receptor-based probes, 1 and 2, appended with two different rhodamine derivatives but differing in their receptor constituents revealed their selective absorption and fluorescence signalling responses to Fe(iii) among all metal ions investigated. Although the output channels in the complexation-induced signalling patterns of these probes are in proximity to each other, the spectroscopic signatures of Fe(iii)-complexation spiro-ring opening of the individual rhodamine derivatives and associated kinetic measurements revealed a preferential coordination affinity of the rhodamine 6G (Rho-6G) component over the rhodamine-B (Rho-B) segment. The Fe(iii)-selective signalling response was observed to be higher in flexible DETA(bis(2-aminoethyl)amine) receptor-incorporated probe 1 than in 2, which incorporates a rigid ethylenediamine receptor. The ratio of the fluorescence of the two wavelength output channels arising from the two different signalling subunits in the architectures of these probes enhances their sensitivity levels in Fe(iii) ion detection. The utility of the Fe(iii)-complexation-induced orange fluorescence output of 1 was demonstrated in the detection and localization of bio-accumulated Fe(iii) ions in root tissues of Grevillea pteridifolia plant species.

A new reversible fluorescent chemosensor based on rhodamine for rapid detection of Al(III) in natural environmental water samples and living organisms

A fluorescence sensor RBKB with high selectivity and sensitivity to Al3+ was designed and synthesized. UV–Vis and fluorescence spectra showed that the probe had a good response to Al3+ in EtOH/H2O (1:1, v/v) solution and t

Fe(III)- and Hg(II)-selective dual channel fluorescence of a rhodamine-azacrown ether conjugate

A rhodamine-azacrown ether conjugate (1) demonstrates Fe(III)-selective green fluorescence, while showing Hg(II)-selective orange fluorescence. This is the first example of rhodamine-based fluorescent probe that shows dual channel fluorescence for two different metal cations.

A FRET based colorimetric and fluorescence probe for selective detection of Bi3+ ion and live cell imaging

A Rhodamine B- quinoline conjugate (RSQ) functions as a colorimetric and fluorescence probe for selective recognition of Bi3+ ion based on CHEF assisted FRET process. RSQ visibly changes its colour and fluorescence profile upon addition of Bis

Strategy to Lengthen the On-Time of Photochromic Rhodamine Spirolactam for Super-resolution Photoactivated Localization Microscopy

Rhodamine derivatives and analogues have been widely used for different super-resolution imaging techniques, including photoactivated localization microscopy (PALM). Among them, rhodamine spirolactams exhibit great superiority for PALM imaging due to a de

Novel Dimethylhydrazine-Derived Spirolactam Fluorescent Chemodosimeter for Tracing Basal Peroxynitrite in Live Cells and Zebrafish

The precise cellular function of peroxynitrite (ONOO-) in biosystems remains elusive, primarily owing to being short of ultrasensitive techniques for monitoring its intracellular distribution. In this work, a novel rhodamine B cyclic 1,2-dimeth

Novel six-membered spiro rhodamine photochromic fluorescent dye containing urea structure as well as preparation method and application of novel six-membered spiro rhodamine photochromic fluorescent dye

The invention discloses a novel six-membered spiro rhodamine photochromic fluorescent dye containing a urea structure as well as a preparation method and application of the novel six-membered spiro rhodamine photochromic fluorescent dye. The novel six-membered spiro rhodamine photochromic fluorescent dye containing the urea structure has a structural general formula as shown in (I). The preparation method comprises the following steps: taking a rhodamine compound, phosphorus oxychloride and dry 1, 2-dichloroethane, reacting at 90 DEG C for 4 hours, cooling to room temperature, removing a solvent, adding dry acetonitrile and a sodium azide saturated solution, stirring at room temperature, drying, filtering, reacting filtrate at 82 DEG C for 40 minutes, adding primary amine, stirring at room temperature, removing the solvent, and purifying by silica gel column chromatography. After the photochromic fluorescent dye disclosed by the invention is irradiated by ultraviolet light with the wavelength of 200-420 nm, the solution color becomes red, and an absorption peak appears at the wavelength of 566 nm; and meanwhile, fluorescence appears at 588nm, the fluorescence intensity is continuously increased along with the prolonging of the illumination time, and the novel six-membered spiro rhodamine photochromic fluorescent dye can be made into stamp-pad ink for counterfeiting prevention.
