چکیده
Homo-metallic metal alkynyl complexes exhibit interesting catenane structures, but their hetero-metallic catenane counterparts are under-developed. In this work, we report rare examples of bimetallic Au–Cu (DtbpC^C ligand; Dtbp 1⁄4 3,5-di-tert-butylphenyl), Au–Ag (BuC^C ligand), and Au–Cu, Au–Ag (C6FluoC^C ligand; C6-Fluo 1⁄4 9,9-dihexyl-9H-fluoren-2-yl) complexes as well as a trimetallic Au–Ag–Cu (C6-FluoC^C ligand) complex, which feature [2]catenane structures. The formation of the [2]catenane structure is significantly affected by the coinage metal ion(s) and change of the structure of the alkynyl ligand. These hetero-metallic [2]catenane structures are strongly luminescent with tunable emission lmax from 503 to 595 nm and F values up to 0.83.

Here, we report on the multicomponent self-assembly and single crystal X-ray diffraction study of a series of three interlocked mixed valence monoand hetero-metallic [2]-catenanes made of [2 2] metallo-grids. They show unique structural features and highlight the essential roles of both the Cu(II)/Cu(I) pair and of the conformationally adaptable organic ligands for achieving catenation of grids.
