Long-lived charge separated (CS) triplet state (2.6 μs) and thermally activated delayed fluorescence (TADF) [ τ = 282 ns (90.4%)/2.4 μs (9.6%)] were observed in an anthraquinone-phenoxazine electron donor-acceptor dyad via the electron spin control method, and emissive 1 CS and non-emissive 3 CS states were discriminated via nanosecond transient absorption spectroscopy and global analysis.
