The shape of supramolecular aggregates based on stereoisomers of p‐ tert ‐butyl thiacalix[4]arenes functionalized with secondary, tertiary amide and hydrazide groups at the lower rim in cone , partial cone and 1,3‐alternate conformations with several metal cations were investigated by atomic force microscopy . The examined p‐ tert ‐butyl thiacalix[4]arenes form host–guest complexes; dimers, spherics ellipsoids and elongated nanoscale particles depending on the conformation of macrocycles, the nature of the binding centers and the nature of the metal cation. Only associates formed by p‐ tert ‐butyl thiacalix[4]arenes with morpholide groups at the lower rim in cone conformation with silver cations exhibited a higher antimicrobial activity .
