Chemists have identified six molecules that can react with a highly toxic gas to produce a blue fluorescent signal (Anal. Chem., DOI: 10.1021/ac300737g). The compounds could find use in a color-based phosgene sensor for the plastics industry, where the gas is commonly used to make building blocks for the materials, the researchers say.

Commercial phosgene sensors detect the notoriously toxic gas based . . .
