AgPF6-promoted oxidation of 5,10,15-trialkyl zinc(II) porphyrins led to formation of meso-meso linked diporphyrins, which were further oxidized with Sc(OTf)(3) and DDQ to give meso-meso, beta-beta, beta-beta, triply linked diporphyrins that exhibited a stronger aggregation propensity than corresponding mesoaryl diporphyrins.
