  • Some open tubular (OT) molecule imprinted polymer (MIP) silica capillary columns with templates of camphor derivatives such as 10-camphorsulfonic acid (10-CSA), 10-camphorsulfonamide (10-CS) and camphor-p-tosyl hydrazone (CTH) have been successfully prepared by the prior generalized preparation protocol. The three MIP thin layers of different templates showed quite different morphologies. The chiral selectivity of each MIP column for the template enantiomers was optimized by changing eluent composition and pH. The optimization conditions were found to be different for the three MIPs. This work suggests prospective successful extension of the generalized preparation protocol for OT-MIP silica capillary columns toward templates of a variety of chemical groups.

  • In this study, we have expanded the applicability of the pre-established generalized preparation protocol to MIPs with a neutral template. The ($4S,5R$hyl-5-phenyl-2-oxazolidinone MIP layer was formed inside a pretreated and silanized fused silica capillary, and its chiral separation performance was examined. Optimization of chiral separation was also carried out. This is the very first report of somewhat successful application of the generalized preparation protocol to a MIP with a genuine neutral template.
