Novel p-tert-butyl thiacalixarenes functionalized with hydrazide groups at the lower rim in cone, partial cone and 1,3-alternate conformations were synthesized and their receptor properties toward metal ions of p- (Al3+, Pb2+) and d- (Fe3+, Co3+, Ni2+, Cu2+, Ag+, Cd2+) elements were investigated by picrate extraction and dynamic light scattering (DLS). It was shown that the p-tert-butyl thiacalixarenes functionalized with hydrazide groups are effective extractants of soft metal cations. The complex stoichiometry depended on the receptor configuration. All the p-tert-butyl thiacalixarene derivatives with hydrazide fragments were able to form nanoscale aggregates but did not show self-association abilities. © 2009 Elsevier Ltd. All rights reserved.
