Fluorinated Fullerenes: Sources of Donor−Acceptor Dyads with [18]Trannulene Acceptors for Energy- and Electron-Transfer Reactions

Fine-tuned control over the donor strength in a series of trannulenes-based donor−acceptor ensembles is used to alter the deactivation path of the photoexcited-state chromophore and to modulate the rates of intramolecular electron transfer. For the first time, a detailed analysis of emission spectra, time-dependent spectroscopic measurements, and electrochemistry prove spectroscopically and kinetically that trannulenes can serve, in a manner...
