The alteration of the existing exciplex wave function is the primary focus. Donor or acceptor components that have been photoexcited produce exciplexes, which cause a charge transfer state to form. By simultaneously exciting the donor and acceptor components of a long-range exciplex system and utilizing an insulating spacer to prevent photo-induced electron transfer between them, the latest study investigates how dual excitation also impacts exciplex formation. The investigation validates the dual excitation contribution and observes that this dual excitation results in more intense exciplex emission when compared to solo excitation of donor or acceptor units.
