One-pot formation and characterization of macrocyclic aromatic tetrasulfonates.
Aromatic tetrasulfonate macrocycles were prepared in one pot by treating arenedisulfonyl chlorides with dihydroxyarenes. X-ray structures revealed that these cyclic molecules have noncollapsible cavities and well-defined conformations resembling the cone and partial cone conformations of calix[4]arenes. Incorporating aromatic residues of different sizes leads to macrocycles with different cavity sizes.
