Description
The development of reversible chemical sensor materials with high stability have received increasing attention. Materials that show dramatic and reversible color changes in the visible or near-infrared (near-IR) spectral regions upon exposure to volatile organic compounds (VOCs) are of particular interest due to potential applications in monitoring waste sites and chemical generating facilities. This research studies platinum-based compounds which exhibit vapochromic behavior.
A new synthesis of trans-dicyano bis(isocyanoparaethylbenzene) platinum(II), Pt(CN-p- (C2H5)C6H4)2(CN)2 is presented. The previously reported route using thermal rearrangement predominately generated the cis isomer.1 This new route can be utilized to predominately generate the trans isomer. Additional studies elucidating the thermal rearrangement of the trans isomer to the cis isomer will be presented. Trans-Pt(CN-p-(C2H5)C6H4)2(CN), was characterized by single crystal X-ray crystallography, 1H NMR spectroscopy, infrared spectroscopy and mass spectroscopy.
