Abstract
Porphyrin-quinone cyclophane 1, in which a tetraphenylporphyrin is linked to a benzoquinone unit by four tetramethylene chains in a face-to-face orientation, was prepared in a multistep synthesis. The structure of 1 and its zinc complex 10 are discussed based on 1H-NMR and in view of photoinduced electron-transfer reactions. A fourfold-bridged porphyrin-quinone cyclophane and its zinc complex were prepared in multistep syntheses; their steric structures are discussed with regard to photoinduced electron-transfer reactions.
