Abstract: In this work, a study of the optical properties of Dibenzylideneacetones (a-c) and 3-Benzylidenethiochroman-4-ones (d-e) is presented. Optical measurements and theoretical approaches are used to establish the contribution of electron donor-acceptor groups in the apparition of fluorescence emission.

Keywords: Dibenzylideneacetones, 3-Dibenzylidenethiochroman-4-ones and fluorescence
