中文摘要： 近年来随着电子工业的迅猛发展，诸如个人电脑，手机，数码相机和媒体播放器等信息技术设备已成为日常生活中不可缺少的一部分。无论从技术角度还是从经济角度来考虑，对新型信息存储材料和器件的研发已成为电子行业急需解决的问题。由于聚合物的电子性质可以通过分子设计和合成等手段调控或剪裁，2005年国际半导体技术发展蓝图（ITRS）将聚合物存储器视为新型存储器件。与无机存储器相比，聚合物存储器具有质量轻、成本低、透明等优点，可以大面积涂布在塑料、玻璃和CMOS集成电路上。本项目拟通过选择能级和推/拉强度匹配的电子给体和电子受体, 调变材料的给/受体比例及其在高分子结构中的位置分布等手段创新设计和制备一系列具有推-拉电子结构特征的高性能高分子信息存储材料。探索电子迁移现象、器件参数（包括写入/擦除电压和速度、ON/OFF 电流开关比、保留时间、再写入能力和循环稳定性等）、材料和器件结构及理化性质之间的关系。

英文摘要： With the rapid development of electronic industries in recent years, information technology devices, such as personal computer, mobile phones, digital cameras and media players have become an essential part of our daily life. From both the technological and economic point of view, the development of novel information storage materials and devices has become an emergent issue facing the electronics industry. Due to the possibility of tailing electronic properties via molecular design and synthesis, polymer electronic memory has been identified as an emerging memory technology since 2005 by the International Technology Roadmap for Semiconductors (ITRS). In comparison to inorganic materials-based memory devices, polymer memories are proposed to revolutionize electrical applications by providing extremely inexpensive, lightweight, and transparent modules that can be fabricated onto plastic, glass, or the top layer of CMOS hybrid integration circuits. The molecular structure of polymers can be tailored by functionalizing them with electron donors and acceptors of different strengths, spacer moieties of different steric effects for the electroactive pendant groups, or nanostructured electroactive materials, to induce different memory behaviors in simple metal/polymer/metal devices. Relationships among the electrical transition phenomena, device parameters (including programming/erasing voltage and speed, ON/OFF ratio, retention time, reprogramming ability and cyclability), materials and device structures, and chemicophysical properties will be explored to understand the solid-state physics and electronics.
