New Three-component Conjugated Polymers and Their Application as Super Rapid-response Fluorescent Probe to DNT Vapor

Abstract Two novel three-component conjugated polymers, P1 and P2, composed of fluorene, carbazole and anthracene / pyrene units, were designed and synthesized. After optimizing the ratio of these three components, their spin-coating films were prepared and used to detect nitro explosives in vapor phase, which present almost instantaneous fluorescence quenching (
