Selective inclusion of phenylenediamine isomers by 1, 1-bis(4-hydroxyphenyl)cyclohexane

Abstract

The title host compound includes para- and ortho-phenylenediamine. The structures of the clathrates are stabilized by a network of hydrogen bonds. Competition experiments in solution and suspension show that the para-isomer is preferentially enclathrated. The inclusion compounds can also be formed by solid-solid reactions.
