Developement of supramolecular metal complexes using aromatic heterocycles

本研究旨在利用杂环金属络合物的特性构建超分子体系，并开发其动态官能化。(1)在阴离子选择性捕集体系的研究中，发现了一种新型的含芳胺基团的吡啶金属络合物，其对阴离子物种的选择性发生了变化，对阴离子球形的识别能力强于四面体。(2)在开发利用光能的超分子体系中，合成了富勒烯非共价键合的新型金属配合物。认为未来通过提高富勒烯的捕集能力可以达到预期的目的。(3)在不对称有机催化剂的研究中，我们成功地引入了吡啶基团，并发现了有趣的立体选择性。我们还成功地在晶体光致变色中找到了一种新的固溶体方法。

This study intended to construct a supramolecular system utilizing the characteristics of the hetero cycles-metal complexes, and develop their dynamic functionality. (1) In the research of anion selective ion-trapping system a new pyridine metal complexes, which possess aromatic amine moieties, the selectivity of anion species changed and the higher recognition ability to anion spherical than tetrahedral was observed. (2) In the development of supramolecular systems that utilize light energy, new metal complexes having non-covalently linked fullerene were synthesized. It is considered possible to achieve the intended purpose by improving the fullerene trapping ability in future. (3) In a study of asymmetric organocatalysts, we succeeded to introduce pyridine moieties and found interesting stereoselectivity. We also succeeded in finding a new solid-solution method in crystalline photochromism.
