Abstract
We leveraged the low dielectric constant of the fluorous phase to improve the photophysical properties of a fluorous pentamethine dye (FCy5) via counterion exchange. We found that larger aryl borate counterions promote charge delocalization across the polymethine chain and increase the photostability (55-fold) and brightness (6-fold) of FCy5.
