Comparison of the Thermodynamic Properties of Particulate and Monolithic Columns of Molecularly Imprinted Copolymers: Comparison of the Thermodynamic Properties of Particulate and Monolithic Columns of Molecularly Imprinted Copolymers. Kim, Hyunjung; Guiochon, Georges (Department of Chemistry, The University of Tennessee, Knoxville, TN 37996-1600, USA). Analytical Chemistry, 77(1), 93-102 (English) 2005 American Chemical Society. CODEN: ANCHAM. ISSN: 0003-2700. DOCUMENT TYPE: Journal CA Section: 37 (Plastics Manufacture and Processing) Section cross-reference(s): 35, 38, 80 A variety of polymn. techniques can be used to prep. molecularly imprinted copolymers (MIPs) for the purpose of the sepn. of enantiomers by HPLC. Unfortunately, the lack of thermodn. and kinetic data characterizing the imprinted polymers prepd. by these different techniques prevents the rational choice of the one most suited for a specific application. We investigated and compared the thermodn. properties of copolymers imprinted for Fmoc-L-tryptophan and prepd. by two different methods. The first was an in situ polymn. method that gives monolithic columns (monolithic MIPs), the second, a traditional method giving bulk MIPs. Examn. of the thermodn. 35737-15-6 and 86123-11-7 are cas registry numbers of chemicals which are used as reagents here. properties on these two different MIPs showed that three types of binding sites coexist on their surface. The highest energy sites adsorb only the imprinted mol. or template. Most of the intermediate energy sites adsorb both the template and its antipode, although part of them may adsorb only the template. Finally, the lowest energy sites provide nonselective interactions of both the template and its antipode. On the nonimprinted copolymer, there are only two types of sites. The high-energy sites have a slightly lower energy that the intermediate sites of the MIPs, and the low-energy sites have properties close to those of the lowest energy sites on the MIPs. The monolithic MIPs have fewer nonselective sites than the bulk MIPs. However, the polar porogen that is needed to prep. the monolithic MIPs neg. affects the enantiomeric sepn. .

Enantioresoln. factors up to 4.82 were obsd. The results were compared with those achieved by the conventional running buffer additives a-, b- and g-CDs. For several examples a steady increase of enantioresoln. with increasing degree of oligomerization was detected. .
