Abstract The impact of various substituent moieties on the molecular framework a conjugated D−A system in resistive switching memory property has been scrutinized through an array novel D‐π‐A molecules. synthesized molecules with triphenylamine (TPA) as electron donor and dicyanovinylindanone (IC) acceptor demonstrated substantial non‐volatile WORM (Write‐Once Read‐Many) behaviour appreciable ON/OFF current ratios up to 105 lowest recorded threshold voltage −0.80 V. well‐balanced combination these potent donating accepting units culminated exceptional intramolecular charge transfer interactions minimal band gap values (1.82–2.31 eV) for molecules, by photophysical electrochemical investigations. These factors, coupled thin‐film morphological studies, corroborated superior performance fabricated devices. A longer retention time 2000s endurance 100 cycles mark stability Moreover, conversion from binary ternary was achieved effective tuning electronic properties systems moieties. Molecular simulation studies revealed that phenomenon arises synergistic interplay trapping processes within systems.
