a) Representation of the guest capturing/releasing procedures of motorized macrocycle 3. b) UV/Vis absorption spectra of the host–guest system before/after photo‐ and thermal isomerization (THF): from [stable‐cis‐3 $\supset$ G1] to [stable‐trans‐3 and G1]. c) Partial ¹H NMR spectra during the isomerization processes of the host–guest system (600 MHz, 203 K, [D₆]acetone, 5 mM), starting from [stable‐cis‐3 $\supset$ G1]. d) UV/Vis absorption spectra of the host–guest system before/after photo‐ and thermal isomerization (THF): from [stable‐trans‐3 and G1] to [stable‐cis‐3 $\supset$ G1] and e) partial ¹H NMR spectra during the isomerization processes of the host–guest system (600 MHz, 203 K, [D₆]acetone, 5 mM), starting from [stable‐trans‐3 and G1].
