In this study we demonstrate that it is possible to ion exchange the small organic cations used to charge balance the dual-pendant sulfonate groups on the particular squaraine system under investigation with metal ions, although we also report that problems with low solubility in water may arise. The ion exchanged squaraine dyes that were water soluble include the lithium, sodium and potassium salts,...
Here we report that the difficulties encountered in the synthesis of a dual-pendant sulfonate bis(indolenine)squaraine dye can be overcome through the use of equimolar amounts of the common reaction catalyst, thus creating an organic salt between the sulfonate groups and the protonated catalyst. Thus, a range of water-soluble dyes can further be prepared, by simply altering the catalyst. Crystal structures...
