Chemical detection is an area of great importance in the shift to more green approaches to industry. Some of the chemical species produced by assorted industries can be harmful, long lived, and challenging to differentiate. Copper(I) iodide (CuI) is a material that readily forms complexes of multiple colors, both under visible and ultraviolet (UV) light. The process of CuI reacting with dimethyl sulfide vapor to produce a color change (vapochromism) has been analyzed to propose mechanistic information about the process. Using the information obtained, a series of potential sensor materials were developed with CuI as the base. The complexes were synthesized using pyridine substituted with electron withdrawing groups to give compounds of the general form (CuI)x(X-Py)y. The various complexes were characterized using elemental analysis, single crystal X-Ray diffraction, and luminescence behavior. The complex (CuI)4(3-PyNO2)4 was particularly promising as a sensing material due to its lack of emission and weak binding characteristics. This material was tested for its performance as a sensor in aqueous media in the detection of pyridine, a common industrial pollutant.
