Ashmore, Jason; Bishop, Roger; Craig, Donald C.; Scudder, Marcia L. published the article 《The effect of chlorine substitution on the inclusion properties of a diquinoline host molecule》. Keywords: chloro substituted diquinoline host mol inclusion compound supramol crystallog.They researched the compound: 2-Amino-5-chlorobenzaldehyde( cas:20028-53-9 ).Application of 20028-53-9. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:20028-53-9) here.
The chloro-substituted diquinoline compounds 7 and 8 have been synthesized as part of our continuing search for new host mols. As intended, the latter forms lattice inclusion compounds with a range of mols., and here the X-ray structures of (8)4·(benzenes)5 and (8)·(toluene) are described. Host 8 exhibits entirely different inclusion behavior compared to its parent non-chlorinated analog 2. Edge-edge double C-H···N synthons, normally ubiquitous in inclusion structures formed by members of this diquinoline host family, vanish when 8 is used. Instead there is increased dependence on halogen-halogen and aryl-aryl interactions. Despite the similarity of the guests, the structures of the two inclusion compounds are very different. Crystal engineering anal. reveals, however, that the supramol. synthons present in the two cases are very similar.
