项目摘要

Supramolecular chemistry which could produce novel functions by, combining small molecules using non-covalent bondings has always attracted a major interest. Macrocyclic compounds consisting of the acethylene units has the inner : cavity. Assembling these macrocyclic compounds, supramolecular structures such as a tube-like structure could be formed, which can be applied for host-guest chemistry and so forth. In this research we proposed the preparation of acethylene-type macrocyclic compounds based on the fluorene units instead of the benzene units and the examination of their aggregation behavior in order to explore the applications. We found out that some functional groups can be introduced into the 1-and 8-positions of the fluorene unit for the first time. Using 3,6-di-tert-butyl fluorene, chloromethylation was carried out under various conditions to give the 1,8-bis(chloromethyl)fluorene from which : the acethylene-type flourene was obtained in several steps. We have investigated various methods to prepare the desired acethylene-type macrocyclic compounds from the fluorene derivatives. As the result we could synthesize the acethylene-type macrocyclic compounds based on the fluorene units as the mixture which contains some analogous compound. We also introduce a long alkyl chain into the outer positions of the fluorene unit. Aggregation behavior of these macrocyclic compounds was investigated in terms of π-π. interaction, hydrogen-bondings and electrostatic interaction. The macrocyclic compounds having a long alkyl chain shows some phases in the solid state. Detail examination is now under way to clarify the liquid crystal properties of these compounds.

超分子化学可以通过使用非共价键将小分子组合来产生新功能，这始终引起了主要的兴趣。由丙基单元组成的大环化合物具有内部：腔。可以形成这些大环化合物，超分子结构，例如类似管的结构，可用于宿主 - 基因化学等。在这项研究中，我们提出了基于氟单元而不是苯单元的丙烯型大环化合物的制备，并检查其聚合行为以探索应用。我们发现，某些官能团可以首次引入氟单元的1和8位。使用3,6-di-teT叔丁基氟，在各种条件下进行氯甲基化，从而从中获得1,8-双（氯甲基）氟的氟化，以从中获得丙烯型氟氟。我们已经研究了各种方法，以制备氟衍生物的所需的丙烯型大环化合物。结果，我们可以根据含有类似化合物的混合物来合成基于氟单元的丙烯型大环化合物。我们还将一条长烷基链引入氟单元的外部位置。这些大环化合物的聚集行为是根据π-π进行的。相互作用，氢键和静电相互作用。具有长烷基链的大环化合物在固态中显示出一些相。现在正在进行细节检查以阐明这些化合物的液晶特性。
