Finally, viewing the difference between Figures and, we find that the S 1 and T 1 states of Cz-BDT have significant locally excited ππ * contributions on BDT whereas S 1 and T 1 are dominated by nπ * character for Cz-AQ. Proceeding to the higher excited states, we find enhanced CT (red) for Cz-AQ. Thus, we can already anticipate that the photophysics of Cz-AQ will be dominated by its CT states whereas locally excited ππ * contributions are more important for Cz-BDT.
