用9-mesityl-10-methylacridinium离子(Mes-Acr(+))共价官能化的金纳米团簇的光激发导致形成电子转移态(Mes(中心点+)-Acr(中心点)),其通过分子内π-π α相互作用与相邻的Mes-Acr(+)形成π-二聚体自由基阳离子。
Photoexcitation of gold nanoclusters covalently functionalized with 9-mesityl-10-methylacridinium ion (Mes-Acr(+)) resulted in the formation of the electron-transfer state (Mes(center dot+)-Acr(center dot)), which forms a pi-dimer radical cation with the neighboring Mes-Acr(+) via an intramolecular pi-pi a interaction.
