(a) Overlap of the CHT-NPA emission and DHI cis absorption. Inset shows PL spectra of CHT-NPA and CHT-DHI-NPA upon excitation at 375 nm. (b) The fluorescence transients of CHT-NPA (excitation at 375 nm) in the absence and in the presence of DHI cis collected at 450 nm are shown. (c) Distribution of donor-acceptor distances between CHT-NPA and the DHI cis-isomer.
