There is a great deal of interest in chemical warfare sensors, such as 2,4-dinitrotoluene (DNT) and 2,4,6-trinitrotoluene (TNT), Trinitro phenol for both military and civilian purposes as well as environmental reasons. The safety of civilians and members of the armed forces is seriously threatened by nitroaromatics in the form of plastic explosives, nerve gas, and toxic spills. Detection of such explosives very important task and study. Here we have developed a sensor that can sense such nitro compounds.
