【 摘 要 】

Co-crystallization of a monofunctionalized hy­droxy pillar[5]arene with 1-octa­namine resulted in the formation of an inclusion complex where the alkyl chain is threaded in the macrocycle cavity, namely 1,2,3,4-(1,4-dimeth­oxy)-5-(1-hy­droxy-4-meth­oxy)-pillar[5]arene–1-octa­namine–water (1/1/1), C44H48O10·C8H19N·H2O. The guest compound is stabilized inside the cavity by hydrogen-bonding and C—H⋯π inter­actions. The water mol­ecule in the asymmetric unit mediates the formation of a supra­molecular dimer by hydrogen-bonding inter­actions. These functionalized-pillararene hosts expand the possibility of exploring more supra­molecular inter­actions with various guest species.
