以芳烃二磺酰氯和二羟基芳烃为原料，一锅法合成了芳香四磺酸大环化合物。X射线结构表明，这些环状分子具有不可塌陷的空腔和明确的构象，类似于杯[4]芳烃的锥形和部分锥形构象。不同大小的芳族残基的取代导致具有不同空腔大小的大环。
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.
