Photocatalytic activity of ZnO composites against rhodamine B and rhodamine 6G
Fibers and Polymers, 2015The development of nanostructures based on interaction of organic matrix and metal oxide particles (such as polypyrrole/zinc oxide composites) introduces interesting advantages due to synergistic/complementary photocatalytic activity of resulting material.

Labeling Mitochondria with Rhodamine 123
Cold Spring Harbor Protocols, 2011INTRODUCTIONRhodamine 123 is a cationic fluorescent dye that is used to specifically label respiring mitochondria. The dye distributes according to the negative membrane potential across the mitochondrial inner membrane. Loss of potential will result in loss of the dye and, therefore, the fluorescence intensity.

Hg2+-promoted photoactivation of triazolyl rhodamine
Photochemical & Photobiological Sciences, 2013Hg(2+) was able to induce the ring-opening of glycosyl triazolyl rhodamines after 26 h incubation at room temperature in MeCN-DMSO (99 : 1). This reaction can be dramatically accelerated by irradiation at 313 nm, by reducing the response time to 2 min.

The action spectra for fading of Rhodamine B (C.I. 45170) are similar for irradiations in aqueous solution and on wool, bleached wool and nylon fabrics, suggesting that the mechanisms of fading are similar in all cases and that the fiber plays no significant photosensitizing role.

Journal of the Society of Dyers and Colourists, 1970
Irradiation with sunlight of an aqueous solution of Rhodamine B (C.I. 45170) (I) produces several detectable products, two of which have been isolated and shown to be chloro‐Rhodamine B (V) and dichloro‐Rhodamine B (IV). These compounds are also obtained from the reaction of Rhodamine B with hydrogen peroxide and from acetone photosensitisation.

The Identification and Purification of Pyronin and Rhodamine Dyes
Stain Technology, 1969The purity of 27 commercial pyronin and rhodamine samples was studied by thin-layer chromatography and visible spectroscopy. Seven different red dyes were detected and separated. The chemical identities of 6 of these were established by nuclear magnetic resonance spectroscopy.

Spectra of the lowest excited singlet states of rhodamine 6G and rhodamine B
IEEE Journal of Quantum Electronics, 1979Excited states of laser dyes were generated in solution by an intense 6 ns laser pump pulse tuned to the absorption maximum of the longest wavelength, ground state absorption band. They were interrogated by a shorter, simultaneous, monochromatic pulse of smaller diameter, concentric and collinear with the pump, having a crossed polarization.

On the aggregation of rhodamine B in ethanol
Chemical Physics Letters, 1988Abstract The dimer and the trimer aggregation constants of the cationic form of rhodamine B are determined in very concentrated ethanolic solutions of the dye. The absorption spectrum, the geometrical structure and the association bonding of the aggregates are discussed and compared with those previously obtained in aqueous solution.

A range of basic dyes and an acidic dye have been dyed onto wool at room temperature using dimethyl sulfoxide as the solvent. When fluorescent Rhodamine dyes are dyed to low depths of shade by this method, the lightfastness of the dyeings is enhanced compared with wool dyed conventionally.

Conjugation of Antibodies to Fluorescein or Rhodamine
2005The isothiocyanate derivative of the fluorophore, fluorescein or rhodamine, is coupled to the amino groups of IgG antibody in a one-step procedure and excess label is removed by gel filtration.
