Isolable selenenic acids were synthesized for the first time by taking advantage of the bridged calix[6]arene frameworks. X-ray crystallographic analysis established the structure of the compound with a cone conformation, where the SeOH functionality is deeply buried in the cavity of the p-tert-butylcalix[6]arene macrocycle. Its thermal stability was so remarkable that no decomposition was observed even after heating at 120 °C for 5 h in CDCl2CDCl2.
