Photoinduced charge separation and recombination in a series of cyclophane-bridged porphyrin-quinone systems (PQ) in toluene solution have been investigated by means of sub-ps time-resolved absorption spectroscopy. Temporal profiles and transient spe

Absorption and emission spectra of the doubly quinone‐bridged porphyrin cyclophanes 1–4 with gradually varied acceptor strength as well as of the single‐bridged analogues 5–9 and 10–13 are reported. Reduction and oxidation potentials of the

Electron transfer in porphyrin—quinone cyclophanes is investigated by fluorescence and absorption spectroscopy with pico- and femto-second pulses. In nonpolar solvents, the S1 state of the porphyrin shows a lifetime from 300 ps up to several nanose

We have measured photoinduced intramolecular electron transfer rates ket in two porphyrin-dichloroquinone cyclophanes varying the polarity, the temperature, and the dielectric relaxation time of the solvent. The reaction is most likely activationless

Chemische Berichte
For studying intramolecular electron-transfer reactions, three groups of double- and single-bridged porphyrin-quinone cyclophanes 1–4, 5–9, and 11–14, resp., with gradual variation of quinone acceptor strengths were synthesized. As key intermed

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
