• Using molecular imprinting method , the 1 , 3 - dimethylxanthine theophylline , tho molecular recognition membranes , containing an segments as membrane formation sites and aa segments as functional sites , were prepared by the phase inversion technique . here , tho was selected as a template molecule . the hydrogen bonding between aa segments and the tho templates was measured by ft - ir and nmr . the tho templates can be removed from the membrane through washing with acetic acid aqueous solution . the permeation of tho through the membranes is far more than that of 1 , 3 , 7 - trimethylxanthine caffeine , caf , which demonstrated the function of tho molecular recognition of the membrane . the results also show that the increase of the tho templates concentration in the cast solution caused an increase of tho amounts taken into the copolymer membrane
  Ft - ir及nmr测试结果表明：制备的高分子膜中， tho模板分子和膜中的丙烯酸功能残基存在着氢键键合作用。大量的极性醋酸水溶液可抽出膜中的模板分子。 tho溶液和与模板分子具有相似结构的1 ， 3 ， 7 -三甲基黄嘌呤咖啡因， caf溶液的基质透过实验结果：进入膜结构中tho分子的量远大于caf分子，这表明制备的高分子膜具有tho分子识别功能。
