Synthesis, Properties and Function of Novel Nano-cyclynes, Nano-rods and Nano-tubes

近年来合成方法学的显著进步使得合成各种具有迷人性质的纳米分子成为可能。具有形状稳定性的杂大环化合物是分子功能化学研究的热点，人们对它们进行了非常活跃的研究，以创造功能性物质和材料。在这种情况下，本论文主要研究了半定形杂大环化合物杂芳环炔和定形氮杂大环化合物芳烃-氮杂芳环炔。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，它们的新功能和特征性质如下：硫杂芳烃环炔：通过特征反应得到有趣的环状Ag（I）配合物。芳烃-氮杂芳烃环炔：（1）尽管具有m键结构，但仍具有很强的发光功能，即使在激发态也具有非常刚性的构象;（2）具有特异的Sb（V）识别功能，是Sb（V）的敏感材料;（3）两个Cu（hfa）_2分子的包结作用，导致形成非常强的发光体。然而，分子功能化学致力于创造具有新的生物、化学和/或物理功能的有机和有机金属分子或分子组装体，目前已成为一个蓬勃发展的领域。因此，所观察到的分子功能对于科学和实际应用是有价值的。

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.
