[reaction: see text] The crystal structure of a tetraurea picket porphyrin-chloride anion complex has previously shown the anion to be situated between two adjacent ureas and hydrogen bonded via four NH protons (J. Am. Chem. Soc. 1998, 120, 11684-116

The synthesis of alpha,alpha-5,10-diurea and alpha,alpha,alpha-5,10,15-triurea picket porphyrins are detailed in this report. In previous reports, these porphyrins, along with alpha,alpha,alpha,alpha-5,10,15,20-tetraurea picket porphyrin, were used t
