Formation of a long-lived charge-separated state of a zinc phthalocyanine-perylenediimide dyad by complexation with magnesium ion.
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.+-PDI.-/Mg2+) in which PDI.- forms a complex with Mg2+.
