Abstract

Photoexcitation of a zinc phthalocyanine-perylenediimide (ZnPc-PDI) dyad affords the triplet excited state without the fluorescence emission, whereas addition of Mg²⁺ to the photoexcited ZnPc-PDI results in formation of a long-lived charge-separated state (ZnPc radical cation-PDI radical anion/Mg²⁺) in which PDI radical anion forms a complex with Mg²⁺. Similarly, Photoexcitation of a trinitrofluorenone-fulluren dyad (TNF-C₆₀) results in formation of long-lived charge separated state in the presence of scandium ion.
