 Abstract: We have measured the fluorescence properties of five cyclophanes containing, in a vertical face-to-face arrangement, a porphyrin as electron donor and one of several substituted quinones as electron acceptor with varying acceptor strength in a series of solvents covering a wide range of polarity. The results of time-resolved fluorescence decay measurements are interpreted in terms of a very fast intramolecular charge separation within 1–10 ps with driving forces decreasing from −ΔGcs = 0.7 to about 0 eV and a charge recombination in the order of 10–200 ps.
