Outline of Annual Research Achievements

本年度は、円偏光発光(CPL)発現の新たなアプローチの確立に向け、誘起CPLの発現機構について詳細な研究を行ってきた。
ナノ繊維状分子集合体が形成するキラル界面(キラルナノテンプレート)にアキラルな発光性分子を濃縮することにより、誘起CPLを発現させるという新たなアプローチの確立および発現機構の調査を行なった。本アプローチの特徴である、様々な組み合わせが可能であるという点を活かし、従来までの合成化学的アプローチでは困難であった系統的な調査に基づき、吸収及び発光における円偏光度(|gCD|および|glum|)の相関性を明らかにした。導き出したこの相関性から、①ナノテンプレートによる二次キラリティと、②発光性分子とキラルナノテンプレート間の強い静電相互作用によって、CPLの発現および強度の制御が可能となることを明らかにした。結果として有機化合物(溶液系)における最高値(|glum| = 0.102)の発現に成功している。
本年度の研究成果は、化学分野において最高峰の学術雑誌の一つであるAngew. Chem. Int. Ed. 2017をはじめとし、学術論文2報および国内外の学会発表12件にて発表している。また、サンクトペテルブルグ(ロシア)で開催された国際学会12th Saint-Petersburg Conference of Young Scientists with international participation "Modern Problems of Polymer Science”において、Best poster presentation awardに選ばれる等,本年度の研究評価が高く評価されている。
