molecule with two electron-withdrawinggroups exhibited excellent ternary memory behavior, while those based on the D–π–A1 or D–π–A2 molecule containing one electron-accepting moiety showed binary memory characteristics. In addition, the bistable memory effects of TPAVC 2 and TPAAH 3-based data storage devices varied from WORM to flash when the acceptor changed from a cyano group to an azobenzene chromophore
