Abstract
The perpendicular arrangement of porphyrin units in dimer 1 is reflected in a large excitonic coupling that leads to splitting of the Soret bands and only modest spectral changes in the Q-bands. Compound 1 and the analogous trimer and tetramer are prepared by oxidative coupling of the corresponding 5,15-diarylporphyrin and are the first examples of compounds having direct meso, meso-linked porphyrin chromophores. Ar = 3,5-tBu2C6H3.
