Excited state properties for the designed boron-doped and nitrogen-doped π-extended nanographenes. a Chemical structures of engineered molecules 4–8. Compound 3 coincides with fr5 in Fig. 2a. b Oscillator strength, fosc, as a function of ∆EST for 3–6 (red squares) against conventional D-A reference TADF emitters (black dots, see chemical structures in Supplementary Fig. 3). c Transferred charge (in |e|) and CT distance (Å), as computed for molecules 3–6. d Emission energies and respective colors for 3–6
