Through-space charge-transfer (TSCT) emitters with high radiative decay rates are very important for their use in electroluminescent devices but have rarely been reported. Here, three TSCT emitters 1–3 with high radiative decay rates of over 107 s−1 are developed by using 4-methyl-9H-xanthene (MeXT) as the rigid linker, 10-phenyldihydroacridine (PhDMAC) as the donor, and 2,4,6-triphenyltriazine (1), 2,4,6-triphenylpyrimidine (2) and 2,4-di-tert-butyl-6-phenyl-1,3,5-triazine (3) as the acceptors. Single-crystal structures and theoretical calcu...
