The changes of optical properties under boundary presence in molecular crystal nanofilm were theoretically investigated in this work. The dispersion law and states of excitons as well as their space distribution along boundary direction have been determined using adjusted Green’s function method and also by combined analytical and numerical calculations. We study the basic micro and macroscopic physical characteristics of symmetric ultrathin molecular crystalline films and one can
see that essential optical properties of these systems arise with perturbation conditions, which appear at their surface layers. On the basis of real and imaginary part of relative permittivity, the absorption reflection and transparent indices were determined, and the influences of boundary parameters on occurrence of a very selective and strictly discrete absorption were analyzed.
