中文摘要： 聚合物电存储材料因其分子设计灵活，成膜性好，易加工，柔性，功耗低以及可实现三维存储技术、大大提高存储容量等优点，在信息存储器件等方面表现出极大潜力。目前已报道的聚合物存储材料与器件都是基于二进制（或二阶）体系。为了进一步提高数据存储的密度和容量，设计和开发具有三阶存储性能的聚合物电存储材料对发展下一代高密度数据存储器件非常重要。然而到目前为止还没有基于单分子聚合物的三阶电存储材料和器件的报道，主要由于设计原理的缺乏。在本项目中，我们旨在实现基于单分子聚合物的新型三阶电存储材料与器件。首先提出全新、有效的设计原理，即将多种存储机制，如构象转变机制与场致电荷转移机制相结合，构建多载流子传输通道，并通过器件优化，实现全新的具有三阶存储性能的聚合物电存储材料与器件。最终通过系统总结材料结构和器件存储性能之间关系，构建具有普适性的三阶聚合物电存储材料设计原理，从而为这一领域的发展提供新的思路和方向。

英文摘要： Polymer electronic memory materials exhibit many merits, such as simplicity of structure, good scalability, low-cost potential, flexibility, 3D-stacking capability, and large capacity for data storage. Hence, they are very promising for application in information storage devices. Nowadays, the realization of polymer memory devices is still restricted to binary materials and based on the electrical bistability (i.e., "0" and "1") in response to an applied electric field. It is highly desirable to increase the number of memory states to three output signals of "0", "1" and "2", and achieve high-density and efficient memory devices. However, such kind of device has been less-explored due to the lack of appropriate design principles. In this project, we hope to realize the ternary memory materials and devices based on single polymer. First, the effective design principle by combining two switching mechanisms in one polymer system to form two conducting channels will be proposed. Based on this principle, polymer materials with ternary memory performances can be prepared, which will be used for fabricating the excellent ternary memory devices through device optimization. Finally, a versatile design principle for polymer ternary memory materials and devices will be constructed, which will provide new idea and direction
