Lipophilic calix[4]arene derivatives that contain two O−C 12 alkyl chains and two SH groups at the lower rim were synthesized and characterized in the 1,2‐ and partial‐cone conformations. Both conformers were treated with Hg 2+ and formed neutral mononuclear Hg 2+ complexes, in which the cation was linearly coordinated to two sulfur atoms. The lipophilic dimercaptocalixarenes were shown to extract Hg 2+ cations exclusively and efficiently from an aqueous phase into chloroform.
