Developing efficient thermally activated delayed fluorescence (TADF) molecule with through-space charge transfer (TSCT) feature remains a great challenge, and theoretical investigation to reveal the inner luminescence mechanisms is highly desired. Herein, photophysical properties of eight TSCT-type TADF molecules are studied by first-principle calculations. Results show that small S1–T1 energy gaps large SOC constants obtained for all molecules, transition can be adjusted acceptor engineering strategy. The ISC RISC processes enhanced adopting A–D–A configurations. Thus, previous experimental measurements reasonably explained, six new proposed.
