Abstract
A composition of matter has the formula:
where n is an integer equal or greater than 1. In another aspect, a method for generating the composition comprises reacting trichloroethylene (TCE) with poly(ethylenimine) in accordance with the formula:
where n is an integer equal or greater than 1. Also, the invention sets forth a sensor to detect trichloroethylene (TCE) in materials. The sensor includes the composition of material that can absorb at least one of infrared (IR) or ultraviolet (UV) or visible (VIS) energies when formed by the reaction of trichloroethylene (TCE) with poly(ethylenimine).
