Abstract
Inclusion compounds consisting of 9,9′-bianthracene host and five chlorinated ethene and ethane guests were prepared. All the guest molecules were included in this host in 1:1 ratio as crystalline inclusion compounds as determined by NMR spectroscopy and thermal analyses. X-ray structures of the inclusion compounds attested that the guest molecules were accommodated in cavities formed by the host molecules and the packing mode was dependent on the size and shape of the guest molecules. Competitive inclusion experiments were performed by using mixed guest systems. The ratios of included molecules indicated that the selectivity decreased in the order of CHCl2CH2Cl, Cl2C=CHCl, cis-ClHC=CHCl, CH2ClCH2Cl, and trans-ClHC=CHCl.
