Abstract Organic semiconductors (OSCs) have been attracted intensive academic and commercial interest due to their intriguing optoelectronic properties and potential applications for electronics. However, the development of n-type OSCs has significantly lagged behind that of p-type counterparts. One general approach towards n-type OSCs is to attach electron-withdrawing cyano or/and imide groups onto the typical p-type OSCs. Here we report the synthesis and optoelectronic properties of three dicyano-substituted 2,3-naphthalimide derivatives. Their low-lying LUMO energy levels from −3.29 to −3.37 eV made them potential candidates for n-type OSCs.
