We presented here a new class of gold­(I)-containing metallosupramolecular cages and cage-built two-dimensional (2-D) arrays of {Au8L2}n (n = 1 or ∞, L = tetrakis-dithiocarbamato-calix[4]­arene, TDCC), 13, which are constructed from the self-assembly of deep-cavitand calix[4]­arene-based supramolecular cages consisting of octanuclear Au­(I) motifs. Synchrotron radiation X-ray diffraction structural analyses of 13 revealed their quadruple-stranded helicate dimeric cage structure and the presence of 2-D arrays of cages linked together by inter- and intramolecular AuI···AuI interactions. Electronic absorption and emission studies of complexes 13 indicated the occurrence of a programmable self-assembly process in a concentration-dependent stepwise manner with the links built via aurophilic interactions. These novel gold­(I) supramolecular cages exhibited green phosphorescence and have been shown to serve as highly selective proof-of-concept luminescent sensors toward AgI cation among various competitive transition-metal ions. %I ACS Publications
