Synthesis of PDK, a novel porphyrin-linked decarboxylate ligand

Research discusses the synthesis of an unique trinuclear ligand system, H(sub)4(PDK) in a multistep protocol using two molecules of Kemp's triacid and one molecule of porphyrin as building blocks. The ligand system is used against porphyrin-based diamine bis(Kemp's triacid)-imide. Data indicate hydrogen bonding interactions between Kemp's triacid units occur.
