✦ Synopsis


Rhodamine 6G has been used as a fluorescence probe in
AOT reversed micelles systems with the different amounts of
solubilized water (hydratation power Ο‰). The saturation of
fluorescence and the lifetime of dye molecules were measured. The
absorption cross section values were calculated from the
saturation curves. We showed the differences in values of the
absorption cross section, lifetime and velocity of fluorescence
saturation in micellar phase with different Ο‰ and in
comparison to bulk phase. Additionally, the structure of hydrated
reversed micelles has been studied by the method of correlation
spectroscopy. The influence of Ο‰ on size and shape of
micelles was detected.

## Abstract The photophysical property of the tricarbocyanine dye IR144 has been extensively studied in non‐aqueous solvents. However, as a potential near‐infrared biomedical imaging probe, the photophysical property of IR144 in water is still little known. So, the aggregation behaviors of IR144 in

Fluorescence quenching in clusters of reverse micelles is analyzed on the basis of a model which takes into account the statistical aspects ofthe interdroplet migration of the excited probe, and the quencher distribution among micelle confinements. The probe's migration frequency between neighboring

In the present work, solvent extraction using reverse micelles is proposed for the removal of organic dyes from water. In this approach, the dye is solubilized in the aqueous core of the reverse micelles, which are present in the organic phase. The organic phase is subsequently separated from the aq
