In low-polarity solvents the yield of the formed singlet oxygen is higher for the molecules of polymethine dyes
(photsensitizers used in chemotherapy), with the anions which contribute to the ionic equilibrium accenting towards the
increased portion of contact ion pairs and also with the anions containing heavy atoms.
