The pivotal role played by potassium ions in the noncovalent synthesis of discrete porphyrin-calixarene nanostructures has been examined. The <i>flattened-cone</i> conformation adopted by the two cavities of octa-cationic calix[4]tube <b>C4T</b> was found to prevent the formation of complexes with well-defined stoichiometry between this novel water-soluble calixarene and the tetra-anionic phenylsulfonate porphyrin <b>CuTPPS</b>. Conversely, preorganization of <b>C4T</b> into a <i>C</i><sub>4v</s ...[more]
