“…In contrast, h PTVM-39 and h PTPM-39 had lower affinity for BSA, with the apparent K d being 137.6 and 95.0 mg/L, respectively. The performance of the TPE-appended maleic acid terpolymers in detecting BSA is compared with other AIE-type fluorescent probes reported in the literature − (Table S2). Although not as sensitive as small molecular AIE-type fluorescent probes for BSA, − the maleic acid terpolymers in our work had superior performance compared with the fluorescent polymer probes in the literature. − They had good response to BSA with a linear range of 0–50 mg/L at [TPE] as low as 2 μM (Figure S27).…”

Multi stimuli-responsive aggregation-induced emission (AIE) active polymers have great application prospects in high-tech innovations. Herein, three types of tetraphenylethylene (TPE)-containing monomers were synthesized and utilized in preparing TPE-appended maleic anhydride terpolymers. After hydrolysis, the produced TPE-appended maleic acid terpolymers have identical linear charge densities but different “primary” structures, which created widely varied microenvironments around the carboxylate and TPE groups. Benefiting from the synergistic interaction of the TPE moiety and the terpolymer conformation change, the TPE-appended maleic acid terpolymers exhibited fluorescence changes in response to multi stimuli, including pH, ionic strength, Ca2+, and bovine serum albumin. On both the “signaling” and the “stimuli acceptor” sides, the multi stimuli-responsive fluorescence behavior was influenced markedly by the terpolymer primary structure. The fundamental insights gained in the present work are important for developing an efficient and versatile stimuli-responsive AIE-active polymer platform for chemo-sensing, bioimaging, and so on.

“…These aqueous conditions are very suitable for many acrylamides and water-soluble acrylates, which have high rates of polymerization. In our previous work, we have exploited the AIEgen-containing initiator tetraphenylethene bromoisobutyrate (TPEBIB) to generate a range of TPE-terminated polyacrylates and polyacrylamides with AIE properties via both Cu(0) wire-mediated and aqueous RDRP, respectively. , AIE-terminated polymers have been reported widely as fluorescence probes for pH, temperature, and in bio-related areas . Among them, TPE-terminated poly(meth)acrylates were reported to have good film-forming ability and thermal stabilities, which could be used as potential fluorescence sensors for explosive detections, − solution viscosity modifiers, and cell imaging …”

A robust wavelength-dependent visible-light-regulated reversible-deactivation radical polymerization protocol is first reported for the batch preparation of >20 aggregation-induced emission (AIE)active polyacrylates and polymethacrylates. The resulting polymers possess narrow molar mass distributions (Đ ≈ 1.09−1.25) and high end-group fidelity at high monomer conversions (mostly >95%). This demonstrated control provides facile access to the in situ generation of complex sequence-defined tetrablock copolymers in one reactor, even while chain extending from less reactive monomers. Polymerizations can be successfully carried out under various irradiation conditions, including using UV, blue, green, and red LED light with more disperse polymers obtained at the longer, less energetic, wavelengths. We observe a red shift and wavelength dependence for the most efficient polymerization using LED illumination in a polymerization reaction. We find that the absorption of the copper(II) complex is not a reliable guide to reaction conditions. Moreover, the reported protocol is readily translated to a flow setup. The prepared AIE-active polymers are demonstrated to exhibit good photopatterning, making them promising materials for applications in advanced optoelectronic devices.

“…Various experimental strategies have been implemented to improve the emissive response of TPT derivatives in the condensed phase. For example, the design of bulky substituents that inhibit nonradiative decay, such as tetraphenylethylene and alkoxy chains, resulted in derivatives with high fluorescence quantum yield in the solid state. , A number of AIE-active polymer structures based on TPT can also feature highly emissive properties. − Despite the previous research, there is not a clear understanding of the excited-state mechanisms in TPT. Having in mind the gradual weakening of solid-state luminescence going from DMTPS, via TPC, to TPT (Figure ), an interesting question arises: How does the substitution of a silicon or carbon atom by sulfur alter the solid-state luminescence of propeller-shaped molecules?…”

Propeller-shaped molecules have received much attention due to their enhanced emission in the condensed phase (aggregation-induced emission, AIE) and their potential use in optoelectronic devices. In this contribution, we examine the excited-state mechanisms of tetraphenylthiophene (TPT), one member of the family that features weaker AIE. We perform a detailed analysis of the potential energy surfaces with special focus on the role of triplet states considering the crystal structure, intermolecular interactions, exciton couplings, and reorganization energies in the vacuum and solid state. In contrast to other members of the propeller-shaped family, nonradiative decay in TPT is driven by bond breaking. Because of the significant spin−orbit couplings along the reaction coordinate, intersystem crossing plays an important role in the mechanism. Our calculations show that aggregation in the solid state hampers the access to internal conversion pathways, however, intersystem crossing is active in the crystal phase, which explains the weak AIE of this molecule. This new understanding of the role of triplet states on the relaxation mechanisms of AIEgens has implications for the design of solid-state highly emissive materials based on TPT.
