最近在合成方法学方面取得的显著进展使人们有可能实现各种具有迷人性质的纳米分子。形状持久的异大环似乎是当前分子功能化学的一个目标，人们对它们进行了非常积极的研究，以创造出功能物质和材料。在这种情况下，本研究将杂环芳烃作为半定形持久杂大环，芳烃-氮杂环作为定形定形氮杂大环。以Sonogashira Pd偶联反应为关键步骤，通过有效的合成方法合成了它们，其新颖的功能和特征性质如下：硫代芳环类化合物：特征反应导致有趣的环状银(I)配合物。芳烃-氮杂芳环化合物：(1)m-键结构的高发光性能，即使在激发态也是非常刚性的构象；(2)特殊的Sb(V)识别功能，这是有价值的Sb(V)敏感材料；(3)两个Cu(HFA)_2分子的包合作用导致形成非常强的发光体。然而，分子功能化学目前已经成为一个蓬勃发展的领域，它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件。因此，所观察到的分子功能具有重要的科学和实际应用价值。

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.
