项目摘要

Recent remarkable progress in synthetic methodology has made it possible to realize various kinds of nanosized molecules with fascinating properties. The shape-persistent heteromacrocycles seem to be a current target in molecular functional chemistry, and their very active investigation has been undertaken to create functional substances and materials. Under such circumstances, this research focuses on heteroarenecyclynes as semi-shape-persistent heteromacrocycles and arene-azaarenecyclynes as shape-persistent azamacrocycles. They have been prepared by the effective synthetic methods using Sonogashira Pd coupling reaction as a key step.Their novel functions and characteristic properties are as follows : Thiaarenecyclynes : characteristic reaction leading to interesting cyclic Ag(I) complex. Arene-azaarenecyclynes : (1)highly light-emitting function in spite of m-bonding structure, and Very rigid conformation even at the excited state, (2)specific Sb(V) recognition function which is valuable as the sensing materials for Sb(V), (3)inclusion function of two Cu(hfa)_2 molecules leading to the formation of very strong luminophore.So far, synthesis, structure, and reaction have been the central theme in chemistry. However, molecular functional chemistry directed towards the creation of organic and organometallic molecules or molecular assemblies with novel biological, chemical, and/or physical functions has currently become a flourishing field. Therefore the observed molecular functions are valuable for scientific and practical applications.

近年来合成方法的显著进步，使各种具有迷人性质的纳米分子成为可能。形状持久的杂大环是目前分子功能化学研究的一个热点，人们对其进行了非常积极的研究，以创造功能物质和材料。在这种情况下，本研究将重点研究半形状持久的杂环类杂环和形状持久的芳烃-氮杂环类杂环。以Sonogashira Pd偶联反应为关键步骤，采用有效的合成方法制备了它们。它们的新功能和特征性质如下：thiaarennecyynes：特征反应生成有趣的环状Ag(I)配合物。芳烃-氮杂芳烃环系化合物：(1)虽然具有m键结构，但具有很强的发光功能，即使在激发态也具有很强的刚性构象；(2)具有特异性的Sb(V)识别功能，可作为Sb(V)的传感材料；(3)两个Cu(hfa)_2分子的包合功能，可形成很强的发光团。迄今为止，合成、结构和反应一直是化学的中心主题。然而，分子功能化学旨在创造具有新的生物、化学和/或物理功能的有机和有机金属分子或分子组合，目前已成为一个蓬勃发展的领域。因此，观察到的分子功能具有重要的科学价值和实际应用价值。
