WebAnalysis of the 2DES spectra in dichloromethane reveals the presence of a state having largely 1 (T 1 T 1 ) character during charge separation. Therefore, the 1 (T 1 T 1 ) multiexciton state plays an important role in the photophysics of this TDI dimer irrespective of solvent polarity. WebThe TDI-Ph-TDI dimers in the films are π-stacked, allowing for through-space interactions between neighboring TDI moieties. As a result, TDI-Ph-TDI undergoes intermolecular SF two orders of magnitude faster than intramolecular SF. Using film-processing techniques, the SF dynamics can be modified.
