为制备腈菌唑（M ）分子印迹聚合物，建立了选择合适的功能单体以及功能单体添加量的方法。利用紫外光谱法研究α-甲基丙烯酸（MAA）、丙烯酰胺（AM）与M 作用形式、作用强度、最佳浓度比和形成的结合位点数。结果表明，M与两种功能单体都会形成氢键；M的三唑环共轭双键的π电子吸收能量跃迁到π*共轭反键轨道，氢键的形成会使π→π*的吸收带发生迁移，最大吸收波长随着体系功能单体浓度增加而发生红移。M与两种功能单体最佳浓度配比分别为：M∶M AA＝1∶4和M ∶AM＝1∶2。M 与两种功能单体都具有结合能力，且结合力较强。采用AM为功能单体合成的分子印迹聚合物对M 具有更好的稳定性和特异识别能力。

To prepare myclobutanil molecularly imprinted polymer ,a method was established for the choice of the appropriate functional monomer and its dosage .UV spectra was applied to study the combination form ,the effect intensity ,the optimal con-centration ratio and the numbers of binding sites between myclobutanil and methyl acrylic acid (MAA) or acrylamide (AM) functional monomer .The results showed that hydrogen-bonding interaction could be formed between myclobutanil and methyl a-crylic acid (MAA) or acrylamide (AM) functional monomer .Theπ electron of the triazole ring conjugated double bond in my-clobutanil could transit to π* conjugate antibonding orbital when it absorbed energy .The formation of hydrogen bond could makeπ→π* absorption band transit .Maximum absorption wavelength produced red shift with the increase in the functional monomer concentration in the system .The research revealed that the optimal concentration ratios between myclobutanil and the two mono-mers were c(M)∶ c(MAA)=1∶4 ,c(M)∶c(AM)=1∶2 .Myclobutanil and the both the functional monomers had the bonding ability ,and strong bonding force .The prepared molecularly imprinted polymer using AM as a functional monomer had better stability and specificity of recognition for myclobutanil .
