Complexation with dichlorotungsten or oxotungsten groups locks chiral calix[4]arenes into rigid cone conformations. The resulting chiral metallocalix[4]arenes such as 1 (picture shows both enantiomers) have been resolved for the first time and are potential building blocks for new materials and supramolecular catalysts.
