Angewandte Chemie, Volume 138, Issue 42, 12 October 2026.Dibenzo[b,d]selenophene (DBSe) π‐core fusion enables rapid triplet–singlet interconversion while preserving the narrowband emission features of multi‐resonance thermally activated delayed fluorescence (MR‐TADF) luminogens. Combined with peripheral donor engineering, this strategy enables systematic emission tuning from green to red, leading to highly ...
