Sulfone Rhodamines for Voltage Imaging
Chemistry – An Asian Journal, 2022AbstractFluorescent indicators that respond to changes in biological membrane potentials provide a powerful complement to existing methods for monitoring neuronal activity. Indicators that absorb and emit in the near infrared window are especially attractive, since lower energy wavelengths excite fewer biological molecules and can penetrate more deeply

The rhodamine B intercalation of montmorillonite
Journal of Colloid and Interface Science, 2004Using photometric methods the dissociation constants and weight fractions of rhodamine B dimer in water solutions at different concentrations were determined. The montmorillonite (SWy) samples were fully intercalated with rhodamine B (RhB) solutions at various monomer/dimer ratios.

Studies of the metabolism of Rhodamine B
Toxicology and Applied Pharmacology, 1961Abstract Rhodamine B (D & C Red No. 19) was metabolized identically in the dog, rat, and rabbit as evidenced by paper chromatograms and paper electrophoretograms of their urines and fecal extracts. The dye was extensively absorbed from the gastrointestinal tract at low dietary levels.

The photophysics of rhodamine B
Journal of Photochemistry, 1982Abstract The effects of solvent viscosity and dielectric constant on the photophysics of rhodamine B in its protonated and zwitterion forms were studied. The internal conversion rate is dependent on the S 1 -S 0 energy separation and increases when this gap is lowered through rotation of the diethylamino groups. Comparison is made with rhodamine 640

A new application of Rhodamine 200 B (Sulfo Rhodamine B)
Dyes and Pigments, 1995Abstract The laser dye Rhodamine 200 B (Sulfo Rhodamine B) (CI Acid Red 52) can be used as a fluorescent counterion for the transfer of various cationic species (e.g. cationic surfactants and crown-complexes of metal ions) into a chloroform phase. The extraction of ionic associates is found to be independent of the acidity of the aqueous phase within

Photochemistry of rhodamine 610
Dyes and Pigments, 1998Abstract Rhodamine 610 was irradiated with a laser emitting a 511 nm. The photodegradation of this dye is very slow (quantum yield = 10 −6 ). Photochemcial reactions were made in ethanol with rhodamine 610 alone, and with additives which quench the single state, the triplet state and radicals.

Optical properties of Rhodamine B and Rhodamine 6G on silver surfaces
Pramana, 1988The transmission spectra of Rhodamine B and Rhodamine 6G dyes coated on silver island films for various thickness were recorded. A strong coupling between the silver particle plasma resonance and the dye molecules is observed. The absorption of dye molecules increases when the absorption band of individual dyes and silver particles overlaps.

Mixed monolayers of a rhodamine derivative
Mendeleev Communications, 2010Mixed monolayers of a rhodamine derivative (GM142) with stearic acid were prepared and their surface-active and optical properties were investigated for application in nanophotonics.
