Meso-β doubly linked Zn(II) porphyrin dimer 1 and anti- and syn-trimers 2 and 3 were synthesized by DDQ-Sc(OTf)3 oxidation of the corresponding meso-β singly linked porphyrin precursors. The absorption and fluorescence spectra and TPA cross-section values of 2 and 3 are distinctly different, reflecting their molecular shapes.
