Abstract

A composition of matter has the formula:

where n is an integer equal or greater than 1. The composition of matter possesses characteristic absorbance behavior with respect to infrared and visible energy, which is used to detect and determine the concentration of TCE. 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).

Claims

1. A composition of matter having a formula of:

where n is an integer greater than 1.

2. A method of generating the composition of claim 1, the method comprising reacting trichloroethylene (TCE) with poly(ethylenimine) in accordance with the Equation:

wherein n is greater than 1.
