Aggregation induced emission (AIE) active cross-linked poly(N-isopropyl acrylamide-co-tetra(phenyl)ethene di-acrylates): sensors for effective nitroaromatics detection in an aqueous environment

The fluorescence of AIE active polymer CP1-4 in water could be quenched by many nitroaromatics. The detection sensitivity of CP1-4 could be greatly improved to the levels as 0.25 ppm by a collapsing-swelling process.
