中文摘要： 本课题将围绕开拓新型功能材料这一主题，以提高材料的非线性光学效应、光电转换效率为导向，开展含有共轭大环配合物的电子给-受分子的设计合成及组装工作。利用共轭大环配合物提供的分子间的π-π堆积、氢键、配位键、静电作用、亲/疏水作用等多种作用力克服D-A分子间固有的静电作用，通过各种（自）组装技术的优化实现对超分子聚集体结构、形貌和功能的调控，提升其功能性质，最终将其应用于非线性光学元件、新型光电传感器件等分子器件的研究。同时，对高级有序超分子聚集体的构筑、结构与性能关系开展理论和实验两方面的研究，探索电子给-受分子结构-高级有序聚集体结构-功能材料性质之间的内在联系，寻求进一步设计合成具有更高性能的新型功能材料的思路和方法。

英文摘要： Electron-transfer processes between a donor and an acceptor play a fundamental role in many applications such as multibit information storage, organic electronics and photovoltaics as well as in basic biological process such as photosynthesis. Therefore, donor-acceptor molecules have attracted increasingly research interests in the field of both material and chemistry. Focusing on the development of new functional materials with good nonlinear optical property or high photoelectric efficiency, the principal investigator will design and synthesize some new donor-acceptor molecules with macrocyclic conjugated structures. The introduction of macrocyclic conjugated structures into donor-acceptor molecular not only induce charming electronic, optical properties, but also provide various non-covalent interactions including hydrogen bonding, amphiphilic effects, electrostatic interaction, ionic bonding, metal coordination, van der Waals forces, and π-π interaction. These non-covalent interactions are expected to be conducive to the formation of well-defined nanostructures. Then, the PI will develop various efficient approaches for combining donor-acceptor molecules into desired functional nanostructure, which is expected to have superior charge-carrier mobility or better charge-separation efficiency. Subsequently the n
