Chemically bonded stationary phases using molecular tweezer hosts: A quantitative HPLC binding assay for nitro-aromatic guests

Chemically bonded stationary phases (CBSPs) were prepared from the following synthetic hosts: bis-acridine, bis-phenanthrene, and bis-trimethoxyphenanthrene molecular tweezers 74, 89, and 92. The retention times of several π-electron deficient guests were measured as a function of temperature on HPLC columns made from each of these CBSPs. Van't Hoff plots were generated to give a total of 22 enthalpies of retention which were compared with the corresponding enthalpies of complexation for the analogous host-guest complex in solution. The correlation was found to be within experimental error of a one-to-one correspondence.
