title: Singlet oxygen generation from Li⁺@C⁺₆₀ nano-aggregates dispersed by laser irradiation in aqueous solution.
abstract: Laser pulse irradiation of a deaerated aqueous solution containing the solid state lithium ion-encapsulated fullerene resulted in the formation of highly dispersed nano-aggregates (Li(+)@C60)n. Photoirradiation of an O2-saturated D2O solution containing (Li(+)@C60)n gave singlet oxygen with 55% quantum yield, leading to efficient double-stranded DNA cleavage.
