WebFor Y6 films, a similar main component in PM6 can be found in the C 1s spectra from C–C bonding in the side chains and aromatic rings ().However, the weak feature at ∼286.3 eV of the Y6 films is slightly different with a more extended shoulder, assigned to contribution from C–S bonds, shake-up and the various bonds between C and N. WebThe short exciton lifetimes of PM6 and Y6 are indicative of ultrafast, non-radiative exciton decay. Intensity dependent analyses of exciton–exciton annihilation yield exciton diffusion lengths for PM6 and Y6 of 2 nm and 4.8 nm, respectively, in Fig. S3, S4 and Table S1 (ESI † ), 44–46 primarily due to their short exciton lifetimes.
