(aromatic region, CD3NO2, 500 MHz, 300 K) a [6]catenane 6, and the mixture after complexation of b 5L +Ag+, c 5K +Ag+, d 5G+Ag+, e 5+5L+Ag+ (1:1:2), and f 5+7+Ag+ (3:1:4). g G only, and h the encapsulation complex after complexation of 9+Ag+ +G (1:1:0.04). Signals with blue circles indicate the aromatic proton signal of G. Signals with asterisks derive from the solvent.
