Abstract
The explosive growth of data and information has increasingly motivated scientific and technological endeavors toward ultra-high-density data storage (UHDDS) applications. Herein, a donor−acceptor (D–A) type small conjugated molecule containing benzothiadiazole (BT) is prepared (NIBTCN), which demonstrates multilevel resistive memory behavior and holds considerable promise for implementing the target of UHDDS. The as-prepared device presents distinct current ratios of 105.2/103.2/1, low threshold voltages of −1.90 V and −3.85 V, and satisfactory reproducibility beyond 60%, which suggests reliable device performance. This work represents a favorable step toward further development of highly-efficient D–A molecular systems, which opens more opportunities for achieving high performance multilevel memory materials and devices.
Highlights
Organic materials have attracted a great deal of attention for a wide range of applications in microelectronics, optoelectronic devices, and intelligent systems [1,2,3,4,5,6,7,8,9,10]
It is noteworthy that tuning the molecular structure and intrinsic property of organic materials can afford multilevel storage and processing operations, which holds great promise for implementing significant ultrahigh-density data storage (UHDDS) applications [6,19,20,21,22]

Summary
Organic materials have attracted a great deal of attention for a wide range of applications in microelectronics, optoelectronic devices, and intelligent systems [1,2,3,4,5,6,7,8,9,10]. It is noteworthy that tuning the molecular structure and intrinsic property of organic materials can afford multilevel storage and processing operations, which holds great promise for implementing significant ultrahigh-density data storage (UHDDS) applications [6,19,20,21,22]. For D–A molecular systems, one key aspect is the utilization of splendid electron acceptors [33,34,35,36]. In this regard, several electron accepting units have emerged as excellent candidates, such as the benzothiadiazole (BT), diketopyrrolopyrrole (DPP), and naphthalimide (NI) functional groups [33,34,35]
