A novel host molecule, 1, suitable for crystalline lattice-type inclusion, has been synthesized, and its cocrystal formation ability has been investigated. Host 1 proved to be of potential use for organic solvent separation and retrieval, and a promi

The X-ray crystal structures of an inclusion compound with 3-picoline and two free host structures, all based on lactic acid but having different aryl substitution and optical resolution states (S or RS), are reported. They are the 2 :1 complex of (S

Solid inclusion hosts, such as derivatives of bis-fluorenyl (1, 2) and maleic acid (3), can include organic solvent vapour molecules such as acetone, cyclohexanone, methanol, ethanol, 1-butanol and dioxane to form stoichiometric inclusion complexes.

The X-ray crystal structures of racemic (1) and S-1,1-diphenyl-1,2-propanediol (2), and of a 2:1 inclusion complex (3) of 2 with 3-picoline are reported. Three different binding schemes characterize the packing of these structures. Only one of the tw

New optically active host compounds for chiroselective crystalline inclusion formation derived from natural lactic acid are synthesized. They enable useful enantiomer separations of different chiral compounds via cocrystallization and sorption on pre

A new type of optically active clathrate formers derived from lactic acid, 1, is described, enabling useful enantiomer separations of different chiral compounds via cocrystallization and, for the first time, via sorption; the X-ray structure of the 2

A series of host molecules derived from tartaric acid have been synthesized in optically resolved and racemic forms. Apart from two endo hydroxyl functions and four bulky aromatic groups (TADDOL-type=α,α,α',α'-tetraphenyl-1,3-dioxolane-4,5-dimeth
