Abstract

A molecularly imprinted polymeric explosives sensor is provided which possesses selective binding affinity for explosives, such as 2,4,6-trinitrotoluene (TNT) and 1,3,5-trinitrobenzene (TNB). The polymeric sensor incorporates a porphyrin which undergoes a detectable change in absorption and/or emission of electromagnetic radiation when the polymer is exposed to explosives.
