Abstract

Using the example of a series of sulfo derivatives of 2-naphthol, it was shown that the charge field formed by the polyelectrolyte coil significantly changes the constants k1 and k−1 of the photoinduced proton transfer reaction, but no noticeable shift in the equilibrium constant K * was found. This observation is fundamentally different from the behavior of these substances in micellar media, where K * increases by an order of magnitude. The binding constants of the dyes with the cationic polyelectrolyte were also determined.
