a A schematic representation of the host–guest chemistry of Ag5L2 in different solvents or solvent mixture. Ag5L2 can encapsulate the studied guests in 5:95 (v/v) CD3CN/CDCl3, CD3CN and acetone-d6. However, in CDCl2CDCl2, the included guests are gradually released from the host–guest complexes. b 1H NMR spectrum (600 MHz, 298 K, 1 mM) of (i) Ag5L2 and (ii) Ad⊂Ag5L2 in acetone-d6 as well as that of (iii) Ag5L2, (iv) Ad⊂Ag5L2 in CD3CN. The DOSY spectrum (v) of Ad⊂Ag5L2 in CD3CN showed that all signals from Ad with Ag5L2 were bound to diffuse at the same rate. c, Time-dependent 1H NMR spectra (600 MHz, 301 K) of the mixture of Ag5L2 and Ad⊂Ag5L2 in CDCl2CDCl2. For experimental details, see Supplementary Method 8, SI.
