A synthetic strategy has been developed to afford porphyrins site-derivatized with the same hydrogen-bond synthon attached directly to the macrocyclic ring. Porphyrin homologues derivatized at the beta and meso positions with an amidinium group form 1:1 supramolecular complexes with benzoate acceptors and show notable differences in their excited-state properties that are dependent on the site of the salt bridge.
