Abstract
- A host–guest supramolecular inclusion complex was obtained from the co-crystallization of A1/A2-bromobutoxy-hydroxy difunctionalized pillar[5]arene (PilButBrOH) with adiponitrile (ADN), C47H53.18Br0.82O10·C6H8N2. The adiponitrile guest is stabilized within the electron-rich cavity of the pillar[5]arene host via multiple C—H...O and C—H...π interactions. Both functional groups on the macrocyclic rim are engaged in supramolecular interactions with an adjacent inclusion complex via hydrogen-bonding (O—H...N or C—H...Br) interactions, resulting in the formation of a supramolecular dimer in the crystal structure.
