Two new axially or peripherally functionalized subphthalocyanines with the decoration of donor-acceptor substituents have been successfully synthesized, characterized and employed in the application of resistive memory device via solution-processable technique. Axially substituted subphthalocyanine shows ternary resistive memory behavior with well-separated current ratios of 1:106:108 between "OFF", "ON1" and "ON2" states, while only binary logic is observed for peripherally substituted subphthalocyanine. Computational studies show the presence of two well-separated charge transfer states in the axially substituted subphthalocyanine, while the charge transfer processes between the peripheral substituents and the subphthalocyanine core are found to be very close in energy. This work has demonstrated the impact of the substituent positioning on the subphthalocyanine-based memory device performance, providing a new research dimension for the future design and development of multistate organic resistive memory.

通过改变亚酞菁核上的取代基定位将电阻记忆行为从二元逻辑切换为三元逻辑

两种新的轴向或外围功能化的亚酞菁具有供体 - 受体取代基的装饰,已成功合成、表征并通过可溶液加工技术应用于电阻存储器件。轴向取代的亚酞菁表现出三元电阻记忆行为,“OFF”、“ON1”和“ON2”状态之间的电流比为 1:106:108,而外围取代的亚酞菁仅观察到二元逻辑。计算研究表明,轴向取代的亚酞菁中存在两种分离良好的电荷转移状态,而外围取代基和亚酞菁核之间的电荷转移过程在能量上非常接近。
