Complexation with diol host compounds. Part 20. Kinetics of desolvation of inclusion compounds of 2,2′-bis(2,7-dichloro-9-hydroxy-9-fluorenyl)biphenyl with 1,4-dioxane and 1,3-dioxolane

Abstract

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 γ-phase before final desolvation to a non-porous α-phase.
