“…Our preliminary investigations into the RAFT polymerization of A‐TPE‐Br using different chain transfer agents (dithiobenzoate‐, trithiocarbonate‐ and xanthate‐type mediating agents) and polymerization solvents suggested that 2‐cyano‐2‐propyl dodecyl trithiocarbonate was an efficient RAFT agent, in terms of the low dispersity of the products with reasonable polymer yields, as shown in Table S1 and Figures S2 and S3 (SI). To our knowledge, this is the first report on the controlled RAFT polymerization of the brominated TPE‐containing acrylate (A‐TPE‐Br), although controlled and free radical (co)polymerizations of nonbrominated TPE‐containing (meth)acrylate has been reported by several groups 24–27,47–51 …”

Aggregation‐induced emission (AIE)‐active nanoparticles (NPs) exhibiting multicolor fluorescence and high‐quantum yields independent of the environment are important for the further development of next‐generation smart fluorescent materials. In this work, AIE‐active amphiphilic block copolymers were designed and synthesized by RAFT polymerization of a brominated tetraphenylethene (TPE)‐containing acrylate (A‐TPE‐Br). The block copolymer exhibited typical AIE effects in selective solvents, which can be explained by hydrophobic TPE aggregated in the core during micelle formation. Luminescent core–shell NPs with a crosslinked AIE core (fixed structure) were synthesized by the Suzuki coupling reaction of the bromine groups of the assembled block copolymer and boronic acid compounds. The NPs composed of TPE/thiophene crosslinked core showed green emission in both diluted state and solid state, implying the ability to fluoresce regardless of environmental changes and molecular dispersion. Multicolor luminescent NPs capable of changing color from blue to red were synthesized by changing the coupling compounds, such as anthracene for electron‐rich units and benzothiadiazole for electron‐deficient units. The effects of the nature of the donor and acceptor, as well as their combination (TPE/donor/acceptor sequence), on the color and fluorescent intensity of the core crosslinked NPs in the nonpolar and polar solvents, and solid state, were investigated.

“…Glycidyl methacrylate (GMA) has been widely used in the modification of polyolefin because of its characteristics of nontoxicity and high activity . Tetraphenylethylene can emit strong light in a solid state as a typical aggregation‐induced emission (AIE) effect, and this can be used in fluorescence labeling …”

Terpolymer poly(α‐methylstyrene‐co‐glycidyl methacrylate‐co‐4‐acryloyl tetraphenylethylene) (PAGT) was synthesized by radical copolymerization using α‐methylstyrene, glycidyl methacrylate, and trace fluorescent monomer 4‐acryloyl tetraphenylethylene. Thermal decomposition of α‐methylstyrene constitutional units in copolymer chains is known to produce macromolecular radicals at temperatures exceeding 90 °C, which may be melt‐grafted to polypropylene (PP) without other initiators by means of extrusion. In this study, the PP‐g‐PAGT microporous material was prepared by casting and stretching. The structure and properties of the PAGT were characterized by Fourier transform infrared spectroscopy, 1H‐nuclear magnetic resonance, and thermogravimetic analysis. The grafting degree and rheological properties proved that the PAGT chains were successfully grafted onto the PP. The uniformity of the PAGT in the PP‐g‐PAGT was observed using a spectrofluorophotometer. The polarity of the cast membrane was characterized by the water contact angle. The results showed that the PAGT evenly grafted onto the PP, and the polarity and hydrophilicity of the cast membranes were improved. The microporous structure of the separator was observed via scanning electron microscopy. Testing of the performance of the lithium battery showed that the impedance decreased and the ionic conductivity increased with the introduction of PAGT onto PP. © 2017 Wiley Periodicals, Inc. J.
