Highly Efficient Synthesis of Ladder-Type Small Molecular and Polymer based on BN-Heteroacene
Ladder-type BN-heteroacene (16-hexadecyl-6,9-diphenyl-6,9,10,16-tetrahydro-5H-benzo[5,6][1,2]azaborinino[4,3-b]benzo[5,6][1,2]azaborinino[3,4-h]carbazole, 4) and the polyheteroacene (P2) consists of ladder-type BN-heteroacene units were obtained with high yields by using a Pd(0)-catalyzed Suzuki reaction followed by ring-closure with PhBCl2. The BN-heteroacene and polyheteroacene show good solub...

A well-defined amphiphilic polymer co-network from precise control of the end-functional groups of linear RAFT polymers
Linear polystyrene (PS) with well-defined molecular structure and accurate numbers of bromo groups on both ends were synthesized via multiple-step alternative RAFT polymerization of N-bromopropyl maleimide and bpinene monomers. The bromo end groups were transformed into the azido moieties via nucleophilic substitution. The reaction of as-synthesized linear PS having a named number of azide group...

Effect of the polymer-substrate interactions on crystal nucleation of polymers grafted on a flat solid substrate as studied by molecular simulations
https://www.sciencedirect.com/science/article/pii/S0032386117306791
The crystallization behaviors of three types of polymer systems grafted on a flat solid substrate with different grafting densities were investigated by dynamic Monte Carlo simulations. For both of the systems with low and medium grafting densities, nucleation induction period becomes shorter with the increasing polymer-subst...

【European Polymer Journal】So2 temperature and oxidation multi-responsive homopolypeptide synthesis characterization and exploration of their potential applications
Abstract:
SO2-responsive homopolypeptide with tri(ethylene glycol), 1,2,3-triazole linkages and N-butylimidazolium iodide pendants (P4) were prepared by the ring-opening polymerization of γ-2-(2-(2-chloroethoxy)ethoxy)ethyl-l-glutamic acid based N-carboxyanhydride then post-polymerization to the side-chain, by the nucleophilic substitution of the chloro group in the presence of NaN3, followe...

An encouraging recyclable synergistic hydrogen bond crosslinked highperformance polymer with visual detection of tensile strength
We have successfully constructed a novel type of recyclable crosslinked protonated polybenzotriazole ether sulfone (PBTSH+), which possessed outstanding thermal stability and mechanical properties. More importantly, the tensile strength of the resulting crosslinked films could be visually detected by taking advantage of the transparency decreasing effect of synergistic hydrogen bonds between pro...

Enhanced carbon dioxide capture in an indolebased microporous organic polymer via synergistic effects of indoles and their adjacent carbonyl groups
A carbonyl-functionalized indole-based microporous organic polymer (PKIN) was designed and synthesized in the presence of the FeCl3 catalyst by a facile direct oxidative coupling reaction. Taking advantage of the synergistic effect of indoles and their adjacent carbonyl moieties on carbon dioxide (CO2), the CO2 uptake capacity of the polymer reaches up to 6.12 mmol g-1 (1.0 bar, 273 K)...

【Chinese Journal of Polymer Science】A biomimetic surface for infection-resistance through assembly of metal-phenolic networks
Abstract:
Despite the fact that numerous infection-resistant surfaces have been developed to prevent bacterial colonization and biofilm formation, developing a stable, highly antibacterial and easily produced surface remains a technical challenge. As a crucial structural component of biofilm, extracellular DNA (eDNA) can facilitate initial bacterial adhesion, subsequent development, and...

【41 Polymer】 Synthesis and linear rheological property of comb-like styrene-based polymers with a high degree of long-chain branching
A series of model comb-like polymers (PSVS-g-PS) with high branching degree were synthesized by nucleophilic substitution reaction between iodinated copolymer of styrene (St) with 4-(vinylphenyl)-1-butene (VSt) (PSVSI, backbone) and living polystyrene lithium (PSLi, side chain). This method is a facile way for modular synthesis of graft copolymers based on living anionic polymerization and hydrozi...
