Outline of Final Research Achievements

We prepared microparticles by the reprecipitation method and measured delayed fluorescence to evaluate the efficiency of singlet fission. It was found that the singlet fission behavior is not significantly different from that of ordinary crystals when the particle size is on the order of several hundred nanometers. However, the efficiency of singlet fission is reduced for the particles prepared by the reprecipitation method due to defects.

Academic Significance and Societal Importance of the Research Achievements

微粒子サイズが数百ナノメートルオーダーの場合、励起状態ダイナミクスは普通の有機結晶での励起状態ダイナミクスと大きく変わらないことが分かった。このことから、普通の結晶の測定から得られた励起状態ダイナミクスは、微小サイズの材料にそのまま適用できることが明らかとなった。このことは、励起子分裂を利用したデバイス開発において重要な知見となったと考えている。
