Optical fiber sensor for volatile organic vapors

摘要

The invention concerns the preparation and description of novel compounds behaving as materials sensitive to various analytes. Two synthetic routes leading to the preparation of the compounds with sensing properties have been tested successfully, although the first route is only valid for anionic L ligands. In the second, more general, route, one of the metallic centers of the double starting salt is eliminated and the sulfur centers are then coordinated. It can be used in the production of chemical sensors as components of the receiving system for the detection of small organic molecules in gaseous phase such as vapors of halogenated or aromatic solvents. Said property has been used in the design of a sensor that is based on fiber optics technology.
