Synthesis and photodynamics of 9-mesitylacridinium ion-modified gold nanoclusters.
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.
