Microscopic theory of a complex charge carrier formed by the binding of a free exciton and an excess electron is briefly described. The potential of interaction between the exciton and excess electron is shown to be attractive as a function of the dipole moments induced by the excess electron on the molecule that carries the exciton. The complex charge carrier, like exciton, is shown to move throughout the molecular crystal.
