[2012][J. Mater. Chem., 2012, 22: 12867-12873]Synthesis and study of low-bandgap polymers containing the diazapentalene and diketopyrrolopyrrole chromophores for potential use in solar cells and near-infrared photodetectors
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 ...

[2014][Adv. Funct. Mater., 2014, 24: 7605-7612]Optimization of Solubility, Film Morphology and Photodetector Performance by Molecular Side-Chain Engineering of Low-Bandgap Thienothiadiazole-Based Polymers
A series of donor–acceptor (D-A) type low-bandgap polymers containing the terthiophene and thieno[3,4-b]thiadiazole units in the main chain but different numbers of identical side chains are designed and synthesized in order to study the effect of side chain on the polymer properties and optimize the performance of polymer photodetectors. Variation in the side chain content can influence the po...

Facile Fabrication of Narrowly-Distributed Polymeric Micelles via Host-Guest Inclusion Complexation of Hyperbranched Polymers and Cyclodextrin and its Two-Dimensional Self-assembly
A novel narrowly-distributed (ND) polymeric micelle obtained in combination with host–guest recognition and self-assembly is reported. First, the adamantyl-terminated hyperbranched poly[3-ethyl-3-(hydroxymethyl)oxetane] (HBPO-AD) was synthesized by esterification of hyperbranched poly[3-ethyl-3-(hydroxymethyl)oxetane] (HBPO) with 1-adamantanecarbonyl chloride. Then the ND polymeric core-sh...

[Polym. Chem.] Topological Analysis and Intramolecular Cyclic Feature Evaluation of Highly Branched Polymers Derived from Am+Bn Step-Growth Polymerization
In this contribution, we investigated the evaluation strategy for intramolecular cyclic features of polymers derived from Am + Bn (m ≥ 2 and n ≥ 2) step-growth polymerization from a topological analysis perspective. The general quantitative relationship between the structural units and the cyclic structures was presented
regardless of the terminal groups of polymers. Further, two strat...

[Polym. Chem.] Miktoarm star polymers with poly(N-isopropylacrylamide) or poly(oligo(ethylene glycol) methacrylate) as building blocks: synthesis and comparison of thermally-responsive behaviors
We synthesized two thermally-responsive miktoarm star polymers in which poly(Nisopropylacrylamide) (PNIPAM) or poly(oligo(ethylene glycol) methacrylate) (POEGMA) served as the thermosensitive building blocks.The obtained miktoarm star polymers were comprised of a b-CD core, a PEG arm and about six PNIPAM or POEGMA arms. Furthermore, the thermally-responsive behaviors of the mik...

[Polymer Chemistry] Three new conjugated polymers based on benzo[2,1-b:3,4-b′]dithiophene: synthesis, characterization, photoinduced charge transfer and theoretical calculation studies
Three new conjugated polymers have been designed and synthesized via the alternate copolymerization of the electron-donating monomer benzodithiophene (BDT) and three different electron-accepting monomers: 5,8-dibromoquinoxaline, 5,8-dibromo-2,3-diphenylquinoxaline, 10,13-dibromodibenzo[a,c]phenazine. The synthesized polymers show good solubility in co...

[J. Phys. Chem. B] Terminal Index: a New Way for Precise Description of Topologic Structure of Highly Branched Polymers Derived from A2+B3 Step-wise Polymerization
Terminal index (TI) was presented as a new characteristic parameter for quantitative description of branched and cyclic topology of highly branched soluble polymers derived from A2 + B3 stepwise polymerization. TI is defined as the ratio of terminal units of an A2 + B3 type highly branched polymer to those in its perfect hyperbranched counterpart. TI is concisely represent...

We synthesized two thermally-responsive miktoarm star polymers in which poly(Nisopropylacrylamide) (PNIPAM) or poly(oligo(ethylene glycol) methacrylate) (POEGMA) served as the thermosensitive building blocks. Firstly, linear methoxypolyethylene glycol (PEG) with β-cyclodextrin (β-CD) bearing about six chlorines as a terminal (PEG-CD-Clx, x z 6) was synthesized. Then, the thermally-respon...

21. Relationship between Frank elastic-constant anisotropies measured from lamellar and of molecular directors of disclinations in main-chain liquid crystalline polymers
The transmission electron microscope technique enables direct visualization of disclination core structure of main chain liquid crystalline polymers. Generally, the lamellar structure, that is a function of type of polymer and molecular length, and of which the thickness is 10-200 nm, can be observed. In terms of distortions in the director field produced by a disclination, the elastic anisot...
