Abstract:
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.
