A new approach for the design of inclusion compounds

Crystal structure and thermal expansion of hexakis(phenylthio)benzene and its CBr4 clathrate

“…The guests can be considered as space fillers that are loosely retained in the lattice; although the thermal parameters of CBr, are small, the CBr, guest molecules can easily be pumped away with destruction of the lattice. This also explains why volatile guests such as CC1, and CH3CC13 are easily lost from HPTB (15).…”

“…HFTB was prepared by a literature route involving the reaction ofC6CI6 with C6HsSNa (15). All single crystals prepared here were obtained by slow evaporation: yellow transparent molecular crystals of HPTB were grown from chloroform; yellow (with orange hue) transparent HPTB-CBr, crystals were grown from a solution of chloroform with excess CSr, (3:1, CBr,-to-HFTB mole ratio).…”

“…This compound is an archetypal example of one of the first premeditated, engineered clathrates (14,15). The hexagonal arrangement of six hydrogen-bonded host molecules of clathrates as in hydroquinone or Dianin's systems (1) basis for the proposal and realization of the design of HPTB and related systems (15). In HPTB systems the hydrogenbonded hexamer is replaced by a single host molecule with a permanent consolidated structure (15) (also vide iifra).…”

Distinct host–guest interaction and subdued fluorescence in a coordination network of 2,3,6,7,10,11-hexakis(phenylthio)triphenylene and silver(I) triflate

“…Star-shaped molecules with multiple rigid and functional side arms such as hexakis(phenylthio)benzene (HPhTB, Chart 1) have been originally studied for their versatile ability as hosts to incorporate guest molecules [1,2]. Such ability is apparently derived from the rather open and radiant shapes which tend to obstruct close packing of the molecules, leaving out empty space that can incorporate various guest molecules.…”

Synthesis and Structures of Novel Multi‐armed Molecules Involving Benzene as a Core and 4‐Phenylthiazole, 4‐Pyrazolylthiazole, or Thiadiazole Units as Arms

“…Since the pioneering work of Vögtle and Weber as well as that of MacNicol et al . on multi‐armed molecules, much attention have been paid to the synthesis of such compounds for their wide range of applications . This class of compounds is considered important hosts for constructing microporous networks possessing selective inclusion properties and their applications in supramolecular host–guest chemistry have been recently reported .…”
