Outline of Final Research Achievements

Highly water-soluble cationic palladium meso-tetrakis(N- methylpyridinium-4-yl)porphyrin, PdTMPyP, as a sensitizer and 9,10-bis[(trimethylammonium-4-yl)- phenyl]- anthracene as an emitter were newly synthesized. Photochemical upconversion (UC) based on them upon excitation at 532 nm was achieved in aqueous solutions for the first time. The UC efficiency was improved by about 30 times by the use of DNA to molecularly organize them in aqueous solutions. The enhancement mechanism was elucidated by lifetime measurements of upconverted fluorescence upon pulsed laser excitation.
Phosphorescence enhancement by more than 90 times was achieved for PdTMPyP immobilized in DNA ultrathin films spin-coated on gold nanoparticle thin films as compared with that on glass substrates. It was attributed to the increased radiative rate of excited triplet states and the electric field enhancement due to localized surface plasmon resonance of gold nanoparticles.

Academic Significance and Societal Importance of the Research Achievements

生体イメージングや太陽電池などで重要な長波長の光を短波長に変換するアップコンバージョンの中で、増感剤と発光剤を用い発光剤三重項消滅に基づく方法(TTA-UC)が低エネルギー利用として注目されているが、環境に優しい全水溶液系はなかった。本研究では世界に先駆けて水溶性増感剤と発光剤によるTTA-UCを実現し、DNAに組織化することで30倍の効率向上を達成し、その機構を解明した。また、金ナノ粒子薄膜上に形成した増感剤を含むDNA超薄膜で燐光の大幅な増強を実現した。このような成果は学術的意義があるばかりでなく、生体イメージングや表示材料などへの展開が期待される。
