Articles comprise transition metal double-complex salts which contain arenyl isonitrile ligands derivatized with long aliphatic chains, the cation being a tetrakis isonitrile platinum ion and the anion being a tetracyanopalladate ion. These double-complex salts exhibit novel vapochromic effects and are useful as personal and badge monitors, theshold monitors, optical waveguide sensors, chemical field effect transistors, and in related monitoring applications.
