We report the synthesis and characterization of novel triphosphine calix[6]arene ligands. These supramolecular wheels, with recognition features governed by the hydrogen‐bonding domain, were employed to synthesize multitasking trinuclear gold(I) complexes as a new platform for the synthesis of interwoven (pseudo)rotaxane species. In parallel, the multivalent, metal‐bonded upper rim displayed catalytic features promoting highly selective gold‐catalyzed cycloisomerization reactions of 1,6‐enynes.
