Supramolecular catalysis [1][2][3] for most chemists is associated with a catalytically active capsule providing either activating
nanoswitches
Heterolepticcomplexation does not only open the way to multicomponent assembly but also to switchable catalysis in coordination-based toggles. An important and widely applicable protocol is the weak-link approach (WLA) that was developed and exploited by Mirkin [116]. It is based on the
[127][128], and others [129][130] that operate at the borderline of dynamic heterolepticcomplexation events, the supramolecular cases selected in the following are characterized by the reshuffling of inter- and intramolecular coordination events to realize different toggling states for catalysis [131

quantitative interconversion is the result of a delicate double self-sorted transformation requiring orthogonality of two heterolepticcomplexation motifs (HETPYP-I and hetero-sandwich complexation at DABCO). Within a selected library of binding guests, DABCO is the only one effecting the interconversion. Due
