Page 28580. We changed “long-range electron exchange−correlation functional set” to “long-range corrected exchange−correlation functional set”. Page 28581. In Figure 4a, the y-axis was incorrectly labeled “Absorption”. We corrected “Absorption” as “Absorbance”. The revised Figure 4 is shown here. No change is made to the caption of Figure 4.
Page 28582. In Table 2, superscripts for PL lifetimes of prompt and delayed components were labeled incorrectly. The superscript “b” should be corrected as “c”. We also corrected minor spacing errorr in the footnotes of Table 2. Finally, in the Supporting Information, we corrected “LongRange Exchange Correlation” as “Long-Range Corrected Exchange−Correlation” throughout. Also, a minor typographic error in a reference was corrected. Those corrections do not affect our conclusions in this work. The authors sincerely regret making the error in the previous report.

Figure 4. (a) Absorption of DPtBn and DPxBn in toluene solution measured at RT. The inset image shows the weak ICT absorption curves in detail. (b) PL spectra of donor unit (PTZ/PXZ) and target TADF (DPtBn/DPxBn) dissolved in toluene solution (concentration, 1.0 × 10−4 M) where the excitation wavelength (λex) was 340 nm. 1 LEs corresponds to locally excited singlet state. (c) PES of electronic states relevant to the transition. Eex designated as the photon energy of λex. (d) PL curves of DPtBn and DPxBn fitted using Marcus framework.
