Photoinduced Electron Transfer in Porphyrin-Quinone Cyclophanes, 5. - Quinone-Porphyrin-Quinone and Quinone-Porphyrin-Donor Cyclophanes: Syntheses, Structures and Electron-Transfer-Related Properties

To study the structure dependence of photoinduced electron transfer between porphyrins and quinones the concept of a new family of porphyrin-quinone cyclophanes with vertical arrangements of porphyrin and quinone units is presented.The syntheses of the quinone-porphyrin-quinone cyclophane 1, the prototype of this series, and of the quinone-porphyrin-donor cyclophanes 12 and 14 are described.Spectroscopic data are discussed with regard to the structures involved and in relation to electron-transfer reactions occurring in these systems.
