Electron transfer in porphyrin-quinone cyclophanes is investigated by fluorescence and absorption spectroscopy with pico-and femto-second pulses. In nonpolar solvents, the S~ state of the porphyrin shows a lifetime from 300 ps up to several nanoseconds, depending upon the number of quinones and upon
