- Abstract
Two small molecular monomers, ph‐TPE and ph‐TPE‐CN, and their homopolymers Poly (ph‐TPE) and Poly (ph‐TPE‐CN) containing tetra phenylethylene and sulfate structures, were synthesized by a sulfur (VI) fluorine exchange click reaction (SuFEx) and radical polymerization. All the monomers and polymers exhibit a typical aggregation‐induced emission (AIE) effect both in the solid state and aggregated state. Moreover, based on the intermolecular charge transfer (ICT) effect between the tetra phenylethylene chromophore and p‐nitrophenol, both polymers could be used for the selective detection of p‐nitrophenol. The detection limit and reactivity coefficient of Poly (ph‐TPE) are 0.081 μM and 5.15×104 M−1, respectively, whereas the detection limit and reactivity coefficient of Poly (ph‐TPE‐CN) are 0.077 μM and 1.81×104 M−1, respectively. This can be attributed to the greater sensitivity of Poly (ph‐TPE‐CN) to p‐nitrophenol than that of Poly (ph‐TPE). This work provides a new methodology for the preparation and broadening application of side‐chain type AIE‐active polysulfate fluorescent probes.
