A Golden Macrocyclization

A phenylene macrocycle was synthesized and utilized as subunit to construct a fourfold Gold(I) metallacycle. The formation of the gold complex shows  size-selectivity compared to an alternative route using platinum(II) corner motifs. Upon reductive elimination a large carbon nanoring was obtained. Investigation as a host for the complexation of large guest molecules was accomplished and revealed high association constants for [6]cycloparaphenylene, fullerene C60, and the larger fullerene C70.
