芳香族アミン類の新奇酸化的変換反応の開発を基盤とする機能性アザπ共役分子の創出

Abstract

Substitution of parts of C=C double bonds of conjugated hydrocarbons with electronegative and isoelectronic C=N moieties often causes drastic improvement in solubility in organic solvent, stability toward air or moisture, and electron-accepting ability. Therefore, aza-containing π-conjugated compounds nowadays constitute a significantly important family of organic functional materials, and thereby much attention has been paid to the elaboration on the development of efficient and selective synthetic methods of such compounds over the last few decades. Recently, we have developed novel synthetic methods of aza-containing π-conjugated compounds that are otherwise difficult to access by conventional methods, starting from aromatic amines as useful building blocks. In this account, the developed reactions along with the physicochemical properties of the novel conjugated compounds are described.
