Abstract
Photoexcitation of gold nanoclusters covalently functionalized with 9-mesityl-10-methylacridinium ion (Mes-Acr(+)) resulted in the formation of the electron-transfer state (Mes(+)-Acr()), which forms a pi-dimer radical cation with the neighboring Mes-Acr(+) via an intramolecular pi-pi interaction.
摘要
金纳米簇与 9-均三甲苯基-10-甲基吖啶鎓离子（Mes-Acr(+））共价功能化后的光激发导致电子转移态（Mes(+)-Acr(））的形成，该电子转移态通过分子内π-π相互作用与相邻的 Mes-Acr(+）形成π-二聚自由基阳离子。
