dc.description.abstract |
The cone conformation of a calixarene has the perfect shape to receive molecules
for host-guest complexation, which makes these molecules desirable in chromatography.
Host/guest complexation is the ability of a host molecule (calixarene) to interact with a
guest molecule (PAH's) or a guest ion (Na+). The objective of this research was the
development of a reliable method for covalent attachment, with high surface coverage, of
p-tert-butylcalix[4]arenes to the surface of silica particles to utilize their host/guest
abilities. A new synthetic method has been developed based on imine formation between
an amino-derived calixarene and amino-derived silica with a glutaraldehyde linker.
Specific types of solute probes (homologous series of PAH's, alkyl benzenes, and
aromatic amines) were used to test the effectiveness of the calixarene stationary phases to
separate in the reversed-phased mode of chromatography. Chromatograms were
compared before and after endcapping the stationary phase, and it was concluded that the
tailing of the peaks and the non-linearity of the log k' vs. number of atoms in a
homologue was indicative of host/guest complexation due to the tethered calixarenes. |
