摘　　要：以25-（硫代烷基烷氧基）-对叔丁基杯[4]芳烃自组装分子作为声表面波（SAW）化学传感器敏感膜材料,以沙磷酸分子为模板分子采用表面印迹技术,通过自组装的方法制备了对有机磷化合物有选择性吸附能力的印迹敏感膜。制备的传感器对目标有机磷化合物有特异响应,在其质量浓度为0.1-0.60 mg/m^3时,其响应频移值与甲基膦酸二甲酯（DMMP）、沙林（GB）的浓度基本呈线性关系;在其质量浓度为0.1 mg/m^3时,响应值为350 Hz。初步讨论了敏感膜聚与有机磷化合物的相互作用过程。对近30种干扰气体进行了比较实验。Surface Acoustic Wave（SAW） chemical sensor for the detection of organophosphorus compounds was prepared on the SAW gold delayline by molecular imprinting technology（MIT） and self-assembly（SAWS） technology with 25-（thioalkyl-alkoxy）-p-tertbutylcalix[4]arene self-assembled monolayers as the sensitive coating and GB as the template reagent.The sensor has special response to target organophosphorus compounds and the response of this sensor to organophosphorus compounds under 0.1 mg/m^3 is 350 Hz.The response frequency increases linearly with the increase of the concentration of DMMP and GB in a range of 0.1 to 0.6 mg/m^3.Possible explanation of interactions between the coatings and the organophosphorus compounds is discussed.
