大环聚合物因其独特的拓扑结构，共轭聚合物因其独特的刚性和光电性能，两者都已成为目前的研究热点。根据结构与性能间的理论依存关系，将大环和共轭特征组合到同一聚合物中，有望实现一些新的物理性能和应用价值。因此，本项目提出以一种新型的大环共轭聚合物为研究对象。拟结合GRIM/KCTP、LAP、AROP聚合机理，利用新型微流反应环化工艺和高效的Glaser反应，高效合成系列Rod、Rod-Coil、Rod-Rod型大环共轭聚合物，并实现各Rod或Coil链段的可控修饰和接枝反应，为高分子化学中复杂结构聚合物的合成提供一种新的思路和方法。拟研究大环共轭聚合物在稀溶液中的组装行为和薄膜中的微相形态，并与线形对照物进行比较，确立聚合物结构与性能间的关系；筛选具有理想微相结构的体系进行光电性能研究和太阳能电池器件构筑，开发聚合物在新材料方面的应用价值。该项目的研究进展，在理论研究和实际应用中将具有重要意义。

Because of the special topology of macrocyclic polymer, and special rigidness and photoelectric properties of conjugated polymer, these two polymers are all becoming the hot topics. According to the theoretical relationship between structures and properties, some novel properties and applications might be realized by the integration of macrocyclic and conjugated characteristics into one polymeric structure. In this project, a novel macrocyclic conjugated polymers will be presented and studied. By perfect combination of Grignard Metathesis Method (GRIM) / Kumada Catalyst Transfer Polycondensation (KCTP), Living Anionic Polymerization (LAP) or Anionic Ring-opening Polymerization (AROP) mechanisms, a novel cyclization technique by Microflow Reaction and efficient Glaser coupling reaction, a series of novel macrocyclic Rod、Rod-Coil、Rod-Rod polymers will be achieved. Also, these cyclic polymers will be modified with functional groups and / or grafted polymers. The successful synthesis of macrocyclic conjugated polymers will enrich the methods to polymers with complicated architectures. Furthermore, the structure-property relationship will be established by comparative study of the micro-phase separation and self-assembly behavior derived from the macrocyclic conjugated polymers and their linear contrasts. By screening the system with ideal micro-phase separation, the photoelectric properties will be investigated and further used to construct the solar cell device, in which the valuable application of synthesized polymers might be confirmed. Importantly, the smooth progress of our project would have great significance in theory and practice.
