Selective uptake : Pillar[5]‐bis‐crown shows the dimetalation via two crown subunits and then uptakes CN(CH 2 ) 2 CN selectively over analogous dinitrile guests with different lengths. This is a chemical example of the adaptive guest binding of biological receptors which are rigidified by metalation to recognise substrates precisely. This work also demonstrates a new perspective on metallosupramolecules of pillararenes. More information can be found in the Communication by Y. Habata, S. S. Lee et al. on page 949.
