Abstract

The host 1,1,2,2-tetraphenyl-1,2-ethane diol was found to form inclusion compounds with the guest toluene and three mono-halo substituted benzenes; chloro-, bromo-, and iodo-benzene. These compounds were characterised by thermal analysis, which showed host:guest ratios of 1:1/2, and their structures were elucidated and compared. Two-, three- and four-component competition experiments were conducted to investigate the selectivity of the host for the respective guests and to determine the separation capabilities of this system.
