中文摘要: 项目主要是通过不同分子长度系列单分散共轭齐聚物和分子量窄分布共轭聚合物的单晶培养和形态结构表征,了解共轭聚合物是折叠链晶体还是伸展链晶体、折叠链或伸展链晶体与共轭聚合物的分子长度是否密切关联、结晶过程的主导作用是柔性侧链还是共轭主链等基本问题。探索半刚性和刚性链高分子晶体生长习性方面的共性规律。

英文摘要: Growth and characterizations of single crystal of conjugated polymer are focused in this project. Oligomers with fixed molecular length and polymers with narrow molecular length distribution are used. Extended- and fold-chain single crystals are expected to be related with molecular length and thickness of lamella crystal. Growth direction is planning to be indicated with flexible side-chain or conjugated main-chain packing. The project is try to understand some of crystalline behaviors of rigid or semi-rigid polymers.
