A series of bis(4-dimethylaminopyridinium)alkane dibromides (1-7) were prepared from the reaction between 4- dimethylaminopyridine (DMAP) and dibromoalkane(s). Electrochemical studies on 1-7 showed two irreversible reduction potentials, which indicated the presence of two DMAP moieties in a compound. Antibacterial and antifungal activities of these compounds were screened.
