Abstract: Polyaniline as an intelligent organic polymer has been noticed since many years ago. Recently there have been some efforts on its applications such as ion selective membranes, batteries, conducting dyes, chemical and gas sensors and etc. Using of conducting polymers as sensors has opened a new field in their applications and it is at the initial steps. On the other hand detection of orgnophosphorus compounds due to their wide applications in insecticides and pesticides, chemical warefare agents are great importance. Regarding this, in present research sensing behavior of molecular imprinting polymer powder base on polyaniline in compare with organophosphorus agronomy pesticides as like as a sample via measurements and FTIR conductance by using a four-point probe method. Among sensing properties studied in this work can mention to analyte concentration, temperature, polymer response time. Molecular imprinting polymer selectivity examined in compare with structure of molecules similar to analyte. In all of the cases conductivity of molecular imprinting polymer remarkable in comparing to molecular non-imprinting polymer because of analyte effect on polymer structure. Preparation process of molecular imprinting polymer and sensing properties did with this method for like compounds namely of diazinon, chlorpyrifos at the results show that molecular imprinted surface in combination with conductometric method is a useful approach for the sensing applications.
