| Outline of Final Research Achievements |
I examined the systematic investigation of azole-fused quinoxaline derivatives on their synthesis and fluorescence properties. About the synthetic method, I could achieve the formation of the corresponding products by three methods based on the type of coupling reaction between two azole rings. From the investigation of the fluorescence in solution, I revealed that the introduction of an additional fused benzene, especially on pyrrole moiety, and the substitution of a nitrogen atom had a strong impact on the fluorescence. Through the analyses of the single crystal structure, I found that the interaction with C-H bond in azole moieties constructs the unique crystal packings even though the resembled molecular structures. And the all compounds except for the triazole derivative gave the fluorescence ability in the solid state. Furthermore, I achieved the functionalization of these compounds by introducing the additional substituents.
