	abstract = {In this study we investigate in detail the photophysics of naphthalene dimers covalently linked by a sulfur atom. We explore and rationalize how the oxidation state of the sulfur-bridging atom directly influences the photoluminescence of the dimer by enhancing or depriving its radiative and non-radiative relaxation pathways. In particular{,} we discuss how oxidation controls the amount of electronic transfer between the naphthalene moieties and the participation of the SOn bridge in the low-lying electronic transitions. We identify the sulfur electron lone-pairs as crucial actors in the non-radiative decay of the excited sulfide and sulfoxide dimers{,} which are predicted to proceed via a conical intersection (CI). Concretely{,} two types of CI have been identified for these dimers{,} which are associated with the photo-induced pyramidal inversion and reverse fragmentation mechanisms found in aryl sulfoxide dimers. The obtained results and conclusions are general enough to be extrapolated to other sulfur-bridged conjugated dimers{,} therefore proportionating novel strategies in the design of strongly photoluminescent organic molecules with controlled charge transfer.},
