Characterization of multifunctional reverse micelles' interfaces using hemicyanines as molecular probes: I. effect of the hemicyanines' structure
(American Chemical Society, 2009-04)
In this work, we report the behavior of two different hemicyanines, trans-4-[4-(dimethylamino)styryl]-Nmethylpyridinium iodide (HC) and 4-[4-(dihexadecylamino)styryl]-N-methylpyridinium iodide (DIA), in water/ sodium ...
Properties of singlet- and triplet-excited states of hemicyanine dyes
(Versita, 2014-06)
The fluorescence emission spectra and fluorescence quantum yields of hemicyanine dyes LDS 698, LDS 722, and LDS 730 were measured in different media. No transient species was detected in the laser flash-photolysis experiments ...
Characterization of multifunctional reverse micelles' interfaces using hemicyanines as molecular probes. II: Effect of the surfactant
(American Chemical Society, 2009-05)
In this work, we have investigated the behavior of the cationic hemicyanine trans-4-[4-(dimethylamino)-styryl]-N-methylpyridinium iodide (HC) in benzene/benzyl-n-hexadecyl dimethylammonium chloride (BHDC)/ water reverse ...
Subtleties of catanionic surfactant reverse micelle assemblies revealed by a fluorescent molecular probe
(IOP Publishing Ltd, 2017-12)
In this work, the absorption and emission behavior of the cationic hemicyanine trans-4-[4(dimethylamino)styryl]-N-methylpyridinium iodide (HC) in reverse micelles (RMs) formed by the catanionic surfactants benzyl-n-hexad ...
