| Research Abstract |
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.
