[Polymers] Synthesis of PNVP-Based Copolymers with Tunable Thermosensitivity by Sequential Reversible Addition-Fragmentation Chain Transfer Copolymerization and Ring-Opening Polymerization
Through the reversible addition–fragmentation chain transfer (RAFT) copolymerization of 3-ethyl-1-vinyl-2-pyrrolidone (C2NVP) and N-vinylpyrrolidone (NVP), a series of well-defined P(C2NVP-co-NVP) copolymers were synthesized (Mn = ca. 8000 to 16,000 and Mw/Mn < 1.5) by using a difunctional chain transfer agent, S-(1-methyl-4-hydroxyethyl acetate) O-ethyl xanthate (MHEX). Copolymerizing kinet...

Immortal ring-opening polymerization of epsilon-caprolactone by a neat magnesium catalyst system: an approach to obtain block and amphiphilic star polymers in situ
Catalyst systems obtained from the inexpensive, ligand-free and commercially available MgnBu2 and alcohols were used for the ring-opening polymerization (ROP) of ε-caprolactone (ε-CL) under mild conditions. The catalytic system of MgnBu2/Ph2CHOH showed very high activity as compared with the system of MgnBu2/Ph3COH, which applied a more bulky methanol derivative. Interestingly, in the pre...

(RSC Advances) Separation of the Molecular Motion from Different Components or Phases using Projection Moving-Window 2D Correlation FTIR Spectroscopy for Multiphase and Multicomponent Polymers
This study developed a new analytical method called projection moving-window 2D correlation FTIR spectroscopy (Proj-MW2D) to separate the molecular motion of groups generated from different components or phases for multiphase and multicomponent polymers. The specific implementation steps for Proj-MW2D were enumerated after the theoretical derivation and algorithm research. Two types of two-compo...

(ACS Applied Materials & Interfaces) A Simple Way to Achieve Legible and Local Controllable Patterning for Polymers Based on Near-Infrared Pulsed Laser
This study developed a simple way to achieve legible and local controllable patterning for polymers based on near-infrared (NIR) pulse laser. The polycarbonate-coated nano antimony-doped tin oxide (nano ATO) was designed as a core-shell structure that was tailored to be responsive to a 1064 nm NIR laser. The globular morphology of polycarbonate-coated nano ATO with a diameter of around 2-3 μm w...

Progress in Photovoltaics, 2016, 130, 319-326. “Multi-channel interface dipole of hyperbranched polymers with quasi-immovable hydrion to modification of cathode interface for high-efficiency polymer solar cells”
The single-junction polymer
solar cells (PSCs) with high power conversion efficiency (PCE) are demonstrated
by firstly incorporating two hyperbranched polymers (CHBPEK
and SHBPES) with carboxylic and sulfonic acid groups to modify the cathode interface. The effect of cathode modification by CHBPEK or SHBPES for conventional PSCs
based on different active-layer materials are systematically investig...

[ACS Appl. Mater. Interfaces] Advanced Aromatic Polymers with Excellent Antiatomic Oxygen Performance Derived from Molecular Precursor Strategy and Copolymerization of Polyhedral Oligomeric Silsesquioxane
In this contribution, the advanced aromatic polymers with excellent antiatomic oxygen (AO) performance were designed and synthesized using molecular precursor strategy and copolymerization of polyhedral oligomeric silsesquioxane (POSS). A soluble poly(p-phenylene benzobisoxazole) (PBO) precursor, that is, TBS–PBO (tert-butyldimethylsilyl was denoted as TBS), was designed to overcome the poor solu...

(JPS Part A) Side-On Main-Chain Liquid Crystalline Polymers Prepared by Acyclic Diene Metathesis Polymerization and Thiol-Ene Click Step-Growth Polymerization
In this manuscript, we design and synthesize a
series of X-shaped mesogenic monomers, bearing two terminal-alkene tails.
Starting from these X-shaped monomers, acyclic
diene metathesis polymerization and thiol-ene polyaddition are applied for the first time to prepare two series
of side-on main-chain liquid crystalline polymers respectively.

The two pairs of structurally related donor–acceptor polymers(P1–P4) derived from diketopyrrolopyrrole(DPP) and diazapentalene(DAP) building blocks were synthesized and compared for their optical and photovoltaic properties with potential applications in solar cells and near-infrared (NIR) photodetectors. Having the electron-rich fluoreneand bis(2′-thienyl)pyrrole (TPT) units as donors, the s...

[2014][Macromol. Rapid Comm., 2014, 35: 1592–1597]Highly Sensitive Dual-Mode Fluorescence Detection of Lead Ion in Water Using Aggregation-Induced Emissive Polymers
A series of fluorene-based conjugated polymers containing the aggregation-induced emissive (AIE)-active tetraphenylethene and dicarboxylate pseudocrown as a receptor exhibits a unique dual-mode sensing ability for selective detection of lead ion in water. Fluorescence turn-off and turn-on detections are realized in 80%–90% and 20% water in tetrahydrofuran (THF), respectively, for lead ion with ...
