中文摘要： 重700公斤《阿凡达》电影拷贝什么时候可以变成一张小小的碟片？现有二进制存储密度已到极限，我们课题组率先在有机小分子突破了三进制存储，其意义是相比二进制在单位面积内信息存储密度呈亿倍增加，从而有望实现700公斤《阿凡达》电影拷贝变成一张碟片。如何在聚合物多进制存储上实现突破，使多进制存储器件的加工工艺变得更加简单？(1)通过分子结构设计，合成系列侧链聚合物，利用侧链功能基团间的电荷转移、氧化-还原、电荷陷阱及构象变化等机理进行组合调控，以及器件界面的调控，实现聚合物材料三进制及四进制性能。(2)借助理论计算对材料性能预测以及对比实验结果，构建多机理调控实现侧链聚合物多进制性能的新机制，为后续多进制侧链聚合物的深入研究奠定理论依据。侧链聚合物多进制存储性能的实现突破了传统无机和有机小分子材料成膜工艺复杂，使器件制备效率提高、成本降低、应用范围更广，加快了多进制信息存储材料走向应

英文摘要： When can we turn 700 Kg weight Avatar movie films into a small disc? Multi-level data storage materials and device can realize it because the multi-level data storage density in per unit area can improve billion times compared with binary system, therefore, multi-level data storage materials and devices have attracted extensive research in recent years. However, most researches are focused on inorganic nanomaterials and small organic molecules. In this project, through design and synthesis of series of pendent polymers , combining of oxidation-reduction mechanism, charge trap, charge transfer and conformational changes mechanisms, and regulation of the device interface , to realize multi-level data storage materials and devices. With the theoretical prediction of material properties as well as comparison of experimental results , we hope to establish the theoretical basis as a guidance to achieve multi-level performance of the pendent polymers in the subsequent research. Multi-level data storage performance based on pendent polymers, breaking the complex film-forming process of the traditional inorganic materials and organic small molecule material, making the device fabrication process more simple, lower cost, higher efficiency, and a more wider range of applications, we believe the realization of multi-level data storage device based on pendent polymers would accelerate the application pace.
