✦ Synopsis

We present time-resolved fluorescence decay measurements on a cylophane-bridged donor-acceptor triad containing a porphyrin and two different quinones in the order porphyrin-quinone,-quinone2. The time scale of photoinduced electron transfer, as well as its energetics, suggests a strong analogy with the primary charge-separation in photosynthetic reaction centers.
