“…The strong structural designability of polymers enables the synthesis of AIE-active polymers with diverse chain topology (linear, star, hyperbrached, cyclic, etc ) and the location of AIEgens at the main chain, side chain, center, or periphery. − For instance, Zhang et al reported a series of AIE-active core-cross-linked miktoarm star copolymers with temperature/pH dual responsiveness. , He et al reported AIE-active hyperbranched poly(β-aminoacrylate)s prepared by spontaneous amino-yne click polymerization . Song et al reported AIE-active linear, , hyperbranched, or cross-linked poly(alkynoate)s prepared by the efficient Ag 2 WO 4 -catalyzed polymerization of CO 2 , diynes, and alkyl dihalides. These studies mainly involved the construction of a certain type of polymer chain architecture for the AIE-active polymers and their usage for particular applications.…”

The rational design and precise synthesis of aggregation-induced emission (AIE) active polymers with diverse macromolecular structures are crucial to their applications in various fields. Herein, four tetraphenylethylene (TPE) bromopropionate initiators with the number of initiation sites of n = 1−4 were synthesized for the first time and applied in the Cu(0)-mediated single-electron transfer living radical polymerization (SET-LRP) of methyl acrylate (MA) and tert-butyl acrylate (tBA). Well-controlled polymerization and high chainend fidelity were confirmed by 1 H NMR and GPC. The produced polymers had diverse topology (linear/star) and the location of TPE moiety (chain-end/midchain/core), which were all precisely dictated by initiator structure. The macromolecular structure had a remarkable effect on the AIE properties of TPE-(PMA) n in THF/H 2 O mixtures and TPE-(PAA) n (obtained after deprotecting tert-butyl groups from TPE-(PtBA) n ) in the B-R buffer solutions of different pH values. The fundamental insights gained into the macromolecular structure−AIE property correlation in our work are important for the design of AIE-active polymer-based functional materials.

“…[ 122 ] Moreover, Qin, Ling, Tang and coworkers also studied the degradation process of the CO 2 ‐based linear and crosslinked unsaturated polyesters, which could be easily visualized by gradually increasing luminescent intensity of the reaction mixtures. [ 123 ] It is interesting to note that the polyesters were successfully degraded by benzamidine into diol and high‐value‐added pyrimidone at 110…”

As an emerging and efficient polymerization methodology, activated internal alkyne-based polymerization has been considered as a powerful tool for the construction of polymers with diverse architectures and versatile functions. This review focuses on the recent progresses in the polymerization using mono-activated, di-activated, in-situ generated, ring-strained ethynyl groups as substrates, coupling with post-modification on premade polymers containing activated internal ethynyl moieties. Representative examples are used to illustrate the fundamental design strategy, the development of polymerization and post-functionalization, along with the properties and potential applications of the prepared polymers. Moreover, the challenges and perspectives in terms of new-type active alkynes, green polymerization methodology, tailored regio-/stereoselectivity modulation, and potentially expanded application in this area are also discussed.

“…As a kind of soft lithography, microcontact printing (μCP) possessed many advantages, including short reaction times, simple large-area patterning, low cost, and so forth. − It allows the manipulator to obtain a relatively delicate pattern without using photomasks or projectors, which are often accompanied by the inconvenient focusing process of the light source.…”

A diselenide bond, as a dynamic covalent bond, is a versatile tool to construct smart interfaces, which can respond to visible light. In this work, we used microcontact printing (μCP) to construct diselenide patterns on quartz substrates. Fluorescent patterns were obtained on the modified surfaces via the visible-lightinduced diselenide metathesis reaction, which allowed the patterning process to be fast, dynamically erasable, and compatible with different fluorescent molecules including rhodamine B and boron-dipyrromethene (BODIPY) used in this work. A variety of analytical methods offered comprehensive evidence for the success of the printing of diselenides here. We further printed diselenide and disulfide intersecting stripes on one single quartz substrate layer by layer and introduced rhodamine B and BODIPY to obtain a multicolored pattern simultaneously. By taking advantage of their responsiveness to different wavelengths, the composite pattern of disulfides and diselenides could be erased by two stepwise stages. The fluorescent images of the modified substrate showed a good agreement with the pattern of the poly(dimethylsiloxane) (PDMS) stamp, indicating the methodology with a potential application for information storage.
