摘要：

The structures of the inclusion compounds of 2,2'-bis(2.7-dichloro-9-hydroxy-9-fluorenyl)biphenyl with 1,4-dioxane and 1,3-dioxolane, with host:guest ratios of 1:3.5 and 1:2 respectively, have been elucidated. Their kinetics of desolvation have been studied and the dioxane inclusion compound desolvates in two distinct steps, each following the first-order kinetic model. The dioxolane inclusion compound desolvates in one step and follows a contracting area model. X-Ray powder photography shows that the dioxane inclusion compound forms a stable intermediate gamma-phase before final desolvation to a non-porous alpha-phase.
