Theoretical investigations on the title compound were carried out by full optimization on its structural unit at the B3LYP/6-31G＊＊ level. And ultimately, the infrared, Raman spectra, electronic absorption spectra, and the relationships between temperature and thermodynamic functions （Hm, Sin, Cpm） were obtained.展开更多

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.展开更多
