摘要

The inclusion compounds of the host 9-(4-methoxyphenyl)-9H-xanthen-9-ol, C23H16O2, with the guests cyclohexane (CHEX), 1,4-dioxane (DIOX), and N,N-dimethylformamide (DMF) have been investigated. Their crystal structures have been determined and correlated with their thermal behavior. Both dioxane and cyclohexane guests gave structures that were isostructural with respect to the host and displayed (Host)OH center dot center dot center dot O(Host) hydrogen bonding. The guests were found on centers of inversion. For the DMF structure, we observed a different packing arrangement with both the host and the guest molecules in general positions, and for the first time, this host displayed (Host)-OH center dot center dot center dot(Guest) hydrogen bonding. Kinetics of desolvation for the 1,4-dioxane and N,N-dimethylformamide compounds were studied. Guest-exchange reactions were also performed.
