Syntheses, conformational and structural analyses of porphyrin‐quinone cyclophanes 2 with naphthalene‐spacers are presented and the findings are compared with data for previously investigated analogous benzene‐spacered compounds 1 . In combination with data for the biphenylene‐ and anthracene‐spacered porphyrin‐quinone cyclophanes 3 and 4 , to be published in following papers, the results reported herein allow some appraisal to be made of the distance dependences of photoinduced electron‐transfer from porphyrin to quinone units.
