Abstract
We consider symmetron model in a generalized background with a hopeto make it compatible with dark energy. We observe a ``no go'' theorem atleast in case of a conformal coupling. Being convinced of symmetronincapability to be dark energy, we try to retain its role forspontaneous symmetry breaking and assign the role of dark energyeither to standard quintessence or F(R) theory which are switchedon by symmetron field in the symmetry broken phase. The scenarioreduces to standard Einstein gravity in the high density region.After the phase transition generated by symmetron field, either theF(R) gravity or the standard quintessence are induced in the lowdensity region. we demonstrate that local gravity constraints andother requirements are satisfied although the model could generatethe late-time acceleration of Universe.
