采用分子自组装印迹技术合成了一种对1-氨基萘有高度选择性的分子印迹聚合物新材料.应用紫外光谱、红外光谱、X射线光电子能谱和~1H核磁共振波谱等研究了印迹聚合物的结合位点和识别机理.结果表明模板分子与功能单体通过氢键作用形成1:1型配合物,配合物的稳定常数K=5.537×10~4L/mol.1-氨基萘分子氨基上的氮原子是质子接受体,功能单体甲基丙烯酸分子羧基上的氢原子是氢键的质子给予体,是与1-氨基萘形成氢键作用的选择性识别位点.利用平衡吸附试验研究了印迹聚合物的结合特性,表明印迹聚合物对1-氨基萘分子具有特异的识别性能.

A new 1-naphthalenamine(NNA) specific molecularly imprinted polymer (MIP) was synthesized based on non-covalent interaction.The molecular recognition characteristics of the template polymer were evaluated by UV,IR,XPS and ~1H NMR.The NNA-MAA complexes of 1 : 1 mole ratio were obtained by nitrogen bonding and the complexes possessed better stabilization (K=5.537 × 10~4L/mol).Furthermore, hydrogen atom of the amino group in 1-naphthalenamine is hydrogen-bond acceptors.Hydrogen atom of the lactam group in methacrylic acid is hydrogen-bond donor, being the predominant binding sites interacting with 1-naphthalenamine.The adsorption characteristics of MIP was evaluated by equilibrium adsorption experiment.The results indicate that MIP performs highly selectivity to 1-naphthalenamine.
