Assessment of Polarity of Comb-Like Polyelectrolytes Using a Pyrene Probe

In recent years, particular attention has been drawn to the investigations on the application of comb-like polyelectrolytes as micellar catalysts. One of the most important parameters that determine the course of a catalytic reaction is the polarity of the medium in a micellar pseudophase. In this work, the polarity of a series of comb-like polyelectrolytes bearing different ionic groups was assessed using the pyrene polarity scale.
