Description
Summary:Oligopyrroles represent a diverse class of molecular receptors that have been utilized in a growing number of applications. Recently, these systems have attracted interest as receptors and chemosensors for hazardous materials, including harmful anionic species, high‐valent actinide cations, and nitroaromatic explosives. These versatile molecular receptors have been used to develop rudimentary colorimetric and fluorimetric assays for hazardous materials. Sequestering, removal, and detection of hazardous materials: The ability to bind and subsequently sense radioactive and explosive materials is critical for protecting the environment and could prove useful in a variety of security‐related applications. Oligopyrroles provide a versatile receptor platform that can be exploited for these purposes, as well as for the recognition of certain potentially hazardous anionic species. The unique electronic features of oligopyrroles make them particularly useful as colorimetric and fluorimetric chemosensors.
