Abstract

The host compound 9,9′-(1,4-phenylene)-bis-(fluoren-9-ol) forms inclusion compounds with pyridine, the isomers of picoline and morpholine. The structures of the inclusion compounds are stabilised by (Host)O–H⋯N(Guest) hydrogen bonds. Unusually, the structure of the host containing 4-picoline and morpholine displays both cis- and trans-conformation. The enthalpy of enclathration of these guests was estimated by packed-column chromatography.
