Conjugated Polymer Sensors: Design Principles Towards Enhanced Versatility
Abstract
A description of how semiconducting fluorescent polymers function as chemosensors for a variety of chemical vapors is presented. Amplification is achieved by transport of optically induced excitations throughout a polymer film. Careful and thoughtful design of polymer chemical structures is crucial to achieving high sensitivity towards nitroaromatic explosives such as trinitrotoluene (TNT) and dinitrotoluene (DNT). These semiconductive materials have been incorporated into functional sensory devices used for ultratrace explosive detection in the search for hidden landmines. Research efforts in our group have been aimed improving the sensitivity, selectivity, and versatility of conjugated polymer sensors through rational molecularly design.
