ラジカルは基本的に不安定であり、⾼い活性を有しています。そのため、ラジカルが発⽣すると思いがけない副反応が進⾏する可能性があります。しかし、その⾼い活性とユニークな反応挙動は有機合成や重合反応において有⽤な⼿段の⼀つです。そのようなラジカルの反応挙動や選択性を明らかにするための基礎研究に取り組んできました。光化学、理論計算、速度論的解析など幅広い分野を横断して、ラジカルの新しい物性と反応性の解明・創出に挑戦していきます。

  • Optically active higher-ordered structures, such as one-handed helical and propeller-shaped structures, can be constructed by folding the π-conjugated system using [2.2]paracyclophane as the chiral crossing unit, leading to circularly polarized luminescence (CPL) properties. Chiral cyclic dimers and trimers were synthesized using planar chiral [2.2]paracyclophane-containing enantiopure ribbon-shaped compounds as the chiral monomers. Unicursal π-conjugated systems were folded at the [2.2]paracyclophane units, and exhibited good photoluminescence quantum efficiencies and CPL anisotropy factors. Opposite chiroptical properties were observed between the dimer and trimer, despite the same absolute configuration of the planar chiral [2.2]paracyclophane units, which was reproduced by theoretical studies.
