Summary: This study demonstrates a one-pot strategy for the molecular design of stimuli-responsive opposite emission/absorption polymer material with unique properties. The nontraditional intrinsic luminescence in the visible region is achieved through reversible addition-fragmentation chain transfer polymerization-induced emission (PIE) of a specific moiety. The opposite emission/absorption properties are derived from the carbocation-quinoid mechanism, enabling fluorescence encryption capability. This work provides a proof of concept for a novel polymer material that might inspire different fields.

Summary: Researchers have successfully synthesized catechol homopolymers with controllable molecular weight and low dispersity by postpolymerization modification of templates bearing active pentafluorophenyl esters. These catechol homopolymers exhibit high reversibility of the catechol/quinone redox couple in both aqueous and organic media. Furthermore, cross-linked polymers can be obtained by copolymerizing the template monomer with a divinyl unit and postpolymerization modification can still be achieved in the swollen network.

Summary: This study reports the use of amino-alkoxy-bis(phenolate) yttrium amido and alkoxide catalysts for controlled metal-catalyzed ring-opening polymerization (ROP) of w-pentadecalactone (PDL). By controlling the reaction temperature and using a chain transfer agent, polymers with high molecular weight can be obtained. Additionally, successful synthesis of block copolymers with different block length and molecular weight was achieved, and the preservation of crystallinity in the block copolymers was confirmed.

Summary: Solid polymer electrolytes are potential alternatives to address safety concerns with liquid electrolytes. A new type of polyether-based single-ion-conducting solid polymer electrolyte was developed, which can be tailored with different functional groups. By introducing tri(ethylene glycol) and succinonitrile, the ionic conductivity of the electrolyte was significantly increased.

Summary: Multi-polymerization is a valuable strategy for tailoring material performances. In this study, diverse polycarbonate terpolymers with different chain structures were fabricated through a dissymmetric Cr complex-catalyzed one-pot terpolymerization. The reaction conditions and 6CC substituents played a critical role in tailoring the sequence distributions of the terpolymers. The obtained terpolymers showed a wide range of glass-transition temperatures based on the polymer architecture.

Summary: In this study, pentafluoro benzyl bromide was used as a clickable initiator for the cationic ring opening polymerization of poly(2-oxazolines) to synthesize various multiblock copolymers. By combining the para-fluoro-thiol click reaction with terminating agents in a one-pot approach, multiblock copolymers such as PEtOx-mb-PMeOx were successfully prepared. Characterization of the polymers was done using SEC, H-1 NMR, and MALDI-ToF mass spectrometry, and the self-assembly properties were studied using DLS and TEM, which showed nanoparticles with diameters ranging from 184 nm to 250 nm for the PEtOx-mb-PMeOx copolymers.

Summary: This contribution provides the current state of the art of metal-catalyzed modification of polyolefins and subsequent polar group incorporation. The direct synthesis from polar monomers is often precluded by catalyst poisoning or uncontrolled side reactions, so modifying a previously prepared polymer through a postpolymerization route is a common alternative. Polyolefins, especially the saturated ones, are challenging substrates to work with due to the limited potential reaction sites within the polymer.

Summary: The study established a 1:1 addition reaction to regulate the sequence of vinyl compounds by enhancing the electrophilicity of DPE derivatives. By sequentially reacting two or three DPE derivatives in increasing order of their electrophilicity, well-defined sequence-controlled polystyrenes were successfully synthesized in a single reaction.
