精密构建一维（1D）或二维（2D）聚合物纳米材料是目前材料研究的前沿领域。目前该类聚合物纳米材料的结构和性能比较单一，其结构与性能关系的理论研究尚未建立。解决该问题的根本在于精密合成结构明确的高分子。本项目拟利用逐步增长法和指数增长法精密合成一系列分子量单分布/序列结构明确的两亲性齐聚物或聚合物，从而精确地调控其组装结构，自下而上地构建结构精致的功能性1D或2D聚合物纳米粒子。项目将详细考查分子量和序列结构对自组装行为及其组装体性能的影响，建立聚合物结构与性能的关系。本项目研究可拓展和丰富高分子的精密合成方法以及多功能1D/2D纳米粒子的精准构建方法，对于研究聚合物结构与性能的关系以及实际应用具有重要意义。

The precision construction of organic one-dimensional (1D) or a two-dimensional (2D) nanomaterials is a cutting-age research area in material science. However, the relationship between the structures and properties of these nanomaterials is rarely exploited and not build. In this project, we use stepwise and exponential growth strategy to synthesize molecularly-defined amphiphilic polymers with monodisperse molecular weight and sequence-defined structure. Therefore, the self-assembly behavior can be well controlled toward the precision construction of functional 1D / 2D nanomaterials. Meanwhile, we will investigate the influence of molecular weight and sequence on self-assembly behavior and properties, and establish the relationship between structure and property of the nanoparticles. This research will greatly expand and enrich the methods for polymer precision and construction of multi-functional 1D/2D nanoparticles, allowing the better understand on the relationship between structure and property, and finally facilitating the practical applications of polymeric nanoparticles.
