Abstract

Dual door entry to exciplex formation was established in a chimeric DNA duplex wherein a fluorescent non-nucleosidic base surrogate (^OxoPyS) is paired against a fluorescent nucleosidic base surrogate (^TPhenB_Do). Packing of the nucleobases via intercalative stacking interactions led to an exciplex emission either via FRET from the donor ^TPhenB_Do or direct excitation of the FRET acceptor ^OxoPyS.
