We report the synthesis and in-depth electrochemical study of two novel electron-accepting sulfonated perylene diimide pyrazolate ligands. Bridging the sulfone moieties of the perylene core unexpectedly affected the optical and electronic properties, as shown by spectroelectrochemical investigation. Notably, we successfully achieved a significant lowering of the LUMO level to -4.83 eV, making the ligand one of the best electron acceptors through a straightforward synthetic procedure. These ligands have the potential for the development of n-type functional materials.
