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測試結果表明：制備的高分子膜中， tho模板分子和膜中的丙烯酸功能殘基存在著氫鍵鍵合作用。大量的極性醋酸水溶液可抽出膜中的模板分子。 tho溶液和與模板分子具有相似結構的1 ， 3 ， 7 -三甲基黃嘌呤咖啡因， caf溶液的基質透過實驗結果：進入膜結構中tho分子的量遠大於caf分子，這表明制備的高分子膜具有tho分子識別功能。 -
