Here, we exploit the similarity of such contributions to develop a fully polarizable mixed QM/discrete/continuum model aimed at studying electronic energy transfer processes in supramolecular systems. In the model, the definition of the three regions is completely flexible and allows us to explore the possibility to describe bridge-mediated contributions by using a polarizable MM description of the linker. In addition, we show that the classical MMPol description of the bridge can be complemented either with an analogous atomistic or with a continuum description of the solvent. Advantages and drawbacks of the model are finally presented and discussed with respect to the system under study.
