ESR and ENDOR spectra are reported of several symmetrical substituted N,N,N′,N′-tetraalkyl-p-phenylenediamine radical cations in solution. Different N,N′-alkyl substituted para-phenylenediamines, like the ethyl, n-propyl, and iso-propyl derivat

Porphyrin quinones are attractive model compounds for mimicking natural electron transfer processes. While the overwhelming majority of studies have been performed with porphyrin p-quinones the isomeric porphyrin o-quinones have been mostly neglected

A series of covalently linked (bacterio)chlorin-quinones were synthesized as model compounds for light reactions in photosynthesis. By replacing the more commonly used porphyrin by chlorins, a closer match to the photosynthetically active chlorophyll

Photosynthesis is one of the most fascinating fields of current interdisciplinary research. It seems miraculous that Nature, in the process of evolution, has managed to bring about a 100% quantum yield in charge separation occurring in the primary pr

The synthesis of biomimetic photosynthetic model compounds, composed of 10, 15, 20-tritolylporphyrins linked to different quinones by cyclohexylene bridges, is described. Cyclic voltammetry measurements show a significant change of the reduction pote

Porphyrin quinones (P-Q's), covalently linked via different aliphatic bridges, have been synthesized and studied in their (porphyrin) cationic and (semiquinone) anionic radical states by EPR, ENDOR and TRIPLE resonance techniques. Time-resolved and s
