有序分子聚集体形成过程的物理化学研究

The order state commonly occurred in the nature is very important to the life process. This project investigated the change process from disorder state to order state in two mimic systems with small molecules. In the system containing some metal elements, the non-covalence eletrostatic interaction plays an important role in the process forming a order system under the guide of the metal element. In the chiral recognize process, the intermolecular hydrogen bonding interaction is important for a successful recognization. It is especially notable that we reported first example of separating a racemic mixture without any chiral separating reagent. In the system containing aromatic ring compounds, the p-p interaction between neighboring aromatic rings is found commonly uccured in the system. The project showed that the formation procedure of the ordered molecular assembles is controlled by the non-covalence interaction between molecules.
