In summary, we have synthesized p-conjugated dendrimers in which donors and acceptors are covalently linked and demonstrated that they exhibited a clear electrical bistability. It is suggested that the electrical bistability would be due to charge transfer between donor and acceptor. The resistance of the device in the OFF state was more than four orders of magnitude higher than that in the ON state. These results provide potential of dendrimers for organic memory device application. The short retention time in organic materials is one of the subjects that should be improved for practical application. We are currently tuning the dendrimer structure to clarify the relationship between the structure and the memory characteristics.

具有电双稳性的共轭树枝状聚合物，用于有机存储应用

总之，我们合成了p-共轭的树枝状大分子，其中供体和受体是共价连接的，并证明它们表现出明显的双电性。建议电双稳态是由于供体和受体之间的电荷转移。处于断开状态的设备的电阻比处于接通状态的设备的电阻高四个数量级。这些结果为有机存储设备应用提供了树枝状聚合物的潜力。在有机材料中的短保留时间是应针对实际应用进行改进的主题之一。我们目前正在调整树枝状大分子的结构，以阐明结构与记忆特性之间的关系。
