    • 摘要: 以二苯甲酰-L-酒石酸(L-DBTA)为模板分子,甲基丙烯酸甲酯(MMA)等为功能单体,乙二醇二甲基丙烯酸酯(GDMA)为交联剂,采用热聚合方法合成了L-DBTA手性分子印迹聚合物.根据Scatchard分析表明L-DBTA手性分子印迹聚合物中只存在一类影响聚合物识别能力的结合位点;293.15 K时结合位点的平衡离解常数为0.11 mmol/L,最大表现结合容量为6.83 mg/g.L-DBTA的MIPs结合热力学研究表明印迹分子L-DBTA与分子印迹聚合物手性识别基团之间的识别机理可以用Langmuir等温吸附描述,L-DBTA的MIPs结合热力学参数如下△H=8.05 kJ/mol,△S=45.85 J/(mol·K),△G298.15=-5.62 kJ/mol,△△H=-1.49 kJ/mol,△△S=3.55J/(mol·K),△△G298.15=-2.55 kJ/mol;L-DBTA与MIPs相互作用速率快,表现活化能为8.05kJ/mol.
