Photoinduced Electron Transfers in Porphyrin-Quinone Cyclophanes, 11: Photoinduced electron transfers in porphyrin-quinone cyclophanes, 11: Synthesis and properties of a vertically stacked porphyrin-quinone(1)-quinone(2) cyclophane

Model compounds for the study of the primary processes in photosynthesis continue to spur chemists on to elaborate syntheses. Latest efforts have resulted in the triple-decker compounds (“triads”) 1 and 2, in which two quinone and one porphyrin, and one quinone and two porphyrin units, respectively, are linked in rigid arrangements
