Outline of Final Research Achievements

In this work, visible-light responsive host complexes with molecular recognition ability have been synthesized. Simple mixing of a visible-light responsive Ru(II) or Ir(III) complex, a Pd(II) or Pt(II) complex, and a tripodal ligand in a 3:3:4 ratio gave self-assembled coordination cages with visible-light-induced catalytic activities. The cages efficiently catalyzed E-Z isomerizations and oxidative cleavages of olefins rather than common photoredox catalysts such as (bpy)3Ru.

Academic Significance and Societal Importance of the Research Achievements

可視光(蛍光灯や太陽光)を用いた有機反応は、物質合成に必要なエネルギーを抑えるのみならず、副生成物の少ないクリーンな反応としても意義深い。可視光応答性の触媒は一般に基質から離れて作用するため、反応の効率や選択性が低いことも多い。本研究では、高効率・高選択性の可視光反応を、標的基質の包接ができる中空錯体を用いて実現する新しい手法を開発した。可視光反応の応用範囲を広げる一歩となる。
