A series of ultrapure‐blue thermally activated delayed fluorescence (TADF) emitters featuring through‐space charge transfer (TSCT) have been constructed by close stacking between the donor and acceptor moieties in rigid heteroaromatic compounds. The obviously accelerated radiative transition of sing...
