functional monomer (MP)_2PT having tertiary aromatic amino group was systhesized from the reaction of N, N-di (2-hydroxypropyl)-p-toluidine with 2-methyl acryloyl chloride. In the presence of organic peroxide, the radical polymerization of (MP)_2PT in toluene took place. The kinetics of (MP)_2PT polymerization and the ESR spectra of LPO-(MP)2PT-MNP systems were determined respectively.

A new molecularly imprinted polymer was synthesized with malachite green (MG) as molecular template, methacrylic acid (MAA) as functional monomer, ethylene dimethacrylate (EDMA) as crosslinker, and azobisisobutyronitrile (AIBN) as initiator. Recognition properties of the MG imprinted polymer were studied by equilibrium adsorption and HPLC. The results showed that the imprinted polymer had good affinity and marked selectivity for MG, and can separate MG with its analogue commendably. The new polymer can be used for the enrichment of MG in complex sample, and can work as separation media to separate and detect MG by HPLC.

A molecular modeling approach was used to elucidate template-monomer interaction and the effect of solvent on the recognition of molecularly imprinted polymers （MIPs）. Ciprofloxacin （CIP） was taken as the template molecule. The methacrylic acid （MAA）, 4-vinyl pyridine （4-Vpy）, acrylamide （AAM）, and 2-（trifluoromethyl） acrylic acid （TFMAA） were taken as the functional monomers, respectively. Density functional theory （DFT） at the LC-WPBE/6-31g（d,p） level has been adopted to investigate the geometry optimization. The NBO charge and the binding energies of CIP with the monomers were carried out. The molecular imprinting mechanism of CIP and the monomers as well as the influence of solvent was also discussed. Results indicate that CIP and the monomers are matchable in steric structure and chemical groups lead to ordered compounds. The interaction between CIP and TFMAA is the strongest, and when the ratio of CIP-TFMA_A is 1：6, the polymer has the lowest energy in toluene. The computational approach has been applied to provide details of interactions between CIP and the monomers. This research will hopefully shed light on the future study of CIP-MIPs.

Two molecularly imprinted polymers binding to analgesic acetanilide were prepared using either dual functional monomers of calix[4]arene derivative and acrylamide or single monomer acrylamide, respectively. The polymers were ground, sieved and investigated by equilibrium binding experiment to evaluate their recognition properties for the template and other substrates. Scatchard analysis showed that homogeneous recognition sites were formed in the imprinted polymer matrix. Our results demonstrated that the polymer using two functional monomers exhibited better selectivity for the template. This study may open new frontiers for the development and application of imprinted polymers, such as drug separation and purification.
