Outline of Final Research Achievements

Syntheses of a series of Donor (D)-pi-Acceptor (A) conjugated enamines were achieved from a hydrosilane reduction of N,N-diarylamides with 1,1,3,3-tetramethyldisiloxane (TMDS) catalyzed by Vaska-type iridium complexes. The catalysts showed high functional group compatibility toward hydrosilane reduction of amides in the presence of halogen, carbonyl, heteroarenes, and nitro groups. Absorption and emission properties were determined both in solution or in solid state by using UV-visible and fluorescent spectra. Nitro-containing D-pi-A enamines showed unusual emission properties including solvatofluorochromic behavior. Treatment of some enamines bearing cyano, acetyl, and formyl groups with B(C6F5)3 resulted in significant red-shifts of both maximum absorption/emission wavelengths with higher quantum yields than those without the additives.

Academic Significance and Societal Importance of the Research Achievements

有機ELディスプレイや感光体といった有機電子材料には、多くの場合、アリールアミン類がドナーとして採用されているが、今回合成した分子は、エナミン骨格を持つ、アミンとは異なるドナー成分を含む新規有機化合物である。アミドからのエナミン合成は、収率や選択性の点から課題が残される現行法とは異なり、高選択的、かつ高い官能基耐性を以て、最大で0.001mol%という極めて少量の触媒量で進行する点で、学術的に非常に価値のある成果である。これらの成果は論文発表に加え、国内外の特許出願に至っている他、産学共同研究へと展開しており、社会還元を十分に見据えた成果といえる。
