“…And, using the 3 σ /S calculation method, the lowest LOD of PLTM‐E‐A to Fe 3+ ions were found to be 7.2 μM. Based on fluorescent probes, LODs of o‐HBA, PVDF‐HPF, and PEN to Fe 3+ ions were reported to be 9.2, 18.4, and 10 μΜ, respectively, comparison with other Fe 3+ ion probes shows the support information in Table S1 34–39 . Our detection limit is well below this range, which indicates the high sensitivity of AIE‐active PLTM‐E‐A to Fe 3+ ions.…”

For the nontraditional aggregation‐induced emission (AIE) active polymers, the heterocyclic structure on the macromolecular backbone and side chains play a crucial role in its fluorescence generation. In this paper, we facilely prepared a series of poly(β‐lactam) derivatives (PLTM) by Staudinger polymerization. As expected, PLTMs with four‐membered heterocycles along the main‐chain shows a remarkable AIE performance with the fluorescence emission at 520 nm, while no fluorescence was observed for both β‐lactam (repeating unit) and a model polymer for PLTM. The fluorescence properties of PLTMs greatly depend on the intramolecular aggregation of β‐lactam structures, the size of the substituents, and appropriate length of CH2 spacer. In addition, PLTMs can specifically detect Fe3+ ions with a limit of detection (LOD) of 7.2 μM even in the presence of other 13 metal ions. Similar to the biological activity of β‐lactam, AIE‐active PLTMs shows a bactericidal effect on Staphylococcus aureus and Escherichia coli with the minimum inhibitory concentration of about 8 and 4 mg/mL. In brief, the preparation and versatility of PLTMs with β‐lactam structure provide useful references for designing other nontraditional AIE‐active polymers as well as for ion detection and antibacterial processes.

Biocompatible fluorescent polymeric nanoparticles (FPNs) are promising luminescent probes in cellular bioimaging, while the fabrication of high-quantum-yield FPN using nonconjugated heterochain polymers derived from step-growth polymerization is still in its infancy. Herein, the nonconjugated polyarylene ether nitrile (PEN) is endowed with aggregation-induced emission (AIE) feature by incorporation of an AIEgen named of 1,2-di(4-hydroxyphenyl)-1,2-diphenylethene into macromolecular backbone. Furthermore, the AIE-active PEN is crosslinked into water soluble fluorescent nanospheres showing good biocompatibility and strong emission ≈480 nm with a quantum yield of 21% in the presence of Ca , which allows the successful bioimaging of cancer cells. Due to the facile fabrication of FPNs and their effective bioimaging performance, the current work will open the way for the biomedical applications of various high performance polyarylene ethers.
