Abstract: The molecularly imprinted technology and the self-assembly technique were used together on the calixarene surface acoustic wave (SAW) chemical sensors to detect organophosphorus compounds. 25-(thioalkyl-alkoxy)-p-tertbutylcalix [4] arene with self-assembled monolayer character was the sensitive coating of the sensors. The sensors had a special response to organophosphorus compounds and the response frequency shift of this sensor to organophosphorus compounds in 0.1mg/m3 was 350Hz. The response frequency increased linearly with the increase of the concentration of DMMP in the range from 0.1 to 0.6mg/m3. The possible explanation of the interaction between the coatings and organophosphorus compounds was discussed.
