Description: One class of sensors relies on vapochromic materials that exhibit color change when exposed to the vapors of volatile organic compounds (VOCs). The present invention is a new vapochromic salt that includes a platinum complex. At room temperature the compound undergoes a color change from orange to red when exposed to vapors of methanol, ethanol, chloroform and acetonitrile.
While other vapochromic materials exist, the compound of the present invention has potentially greater sensitivity and lower cost.
