Chiral Separation Ability of Metal-Complexing Imprinted Polymer for L-mandelic Acid

Liu Ying,Ding Guosheng,Xu Xiuming,Hao Weiqiang,Wei Guilin,Wang Junde~*(Dalian Institute of Chemical Physics,Chinese Academy of Sciences,Dalian 116012)  
Metal-complexing imprinted polymer for L-mandelic acid was prepared using Cu(Ⅱ)-\iminodiacetic acid as functional monomer,trimethylolpropane trimethacrylate as crosslinker and methanol as porogenic agent.Chiral separation ability of metal-complexing imprinted polymer to D,L-mandelic acid was investigated by high performance liquid chromatography.The mobile phase conditions(pH,methanol content, buffer concentration,etc.) could significantly influence the chiral separation ability of metal-complexing imprinted(polymer).Highly chiral selective to the template molecule by metal-complexing imprinted(polymer) was achieved as pH 7-9 of the mobile phase;the chiral separation ability of metal-complexing(imprinted) polymer was increased with the increase of methanol content and buffer concentration.It is suggested the feasibility to prepare highly selective molecularly imprinted polymer in polar solvent.
