[Chem Commun] A Microcontacting Printing Induced Supramolecular Self-Assembled Photo Active Surface for Patterning Polymer Brushes
A facile and robust strategy for creating micropatterned polymer brushes via the combination of micro-contact printing (μCP) induced supramolecular self-assembled photo active surface with subsequent self-initiated photografting and photopolymerization (SIPGP) is reported. The results contribute to polymeric functionalization on a wide range of hydroxylated surface or graphene based materials

[Colloid and Polymer Science] Detecting the Cross-linking Process of Hybrid Large-Compound Vesicles by an Electrochemical Method
A simple electrochemical method of cyclic voltammetry (CV) was exploited to detect the cross-linking process of hybrid large-compound vesicles (LCVs) bearing
electrochemically reactive ferrocene group inside. Results indicated that the CV behavior of LCVs deposited electrode was relative to the cross-linking degree of LCVs. It was found that oxidation peak potential became more positive and diffus...

[Colloid and Polymer Science] Coating Sulfonated Polystyrene Microspheres with High Dense Gold Nanoparticle Shell for SERS Application
The fabrication of high dense gold nanoparticles (NPs) coated sulfonated polystyrene (PS) microspheres and their application in surface-enhanced Raman spectroscopy (SERS) were reported. After the preparation of PS microsphere using dispersion polymerization and subsequent sulfonation, [Ag(NH3)2]+ ions were adsorbed on the surfaces of the sulfonated-PS microspheres and then reduced to silver ...

Hemiphasmidic Side-Chain Liquid Crystalline Polymer: From Smectic C Phase to Columnar Phase with a Bundle of Chains as Its Building Block
We synthesized a new hemiphasmidic side-chain liquid crystalline polymer (P-n, n is the number of carbons in alky tail of the side chain, n = 4?12) using free radical polymerization. The side chain of P-n has a biphenyl in the middle, linked to the polystyrene backbone and to the terminal phenyl group with three alkyl tails via only methyleneoxy units. Upon increasing n,...

An H-Shaped Polymer Bondingb-Cyclodextrin at Branch Points: Synthesis and Influences of Attachedb-Cyclodextrins on Physical Properties
We report on the synthesis of an H-shaped polymer bondingb-cyclodextrin (b-CD) at branch points and influences of attachedb-CD on physical properties. First, a poly(ethyleneglycol)(PEG)-based functional macroinitiator bearing two azidos and four chlorines at chain-ends (PEG-2N3(-4Cl)) was prepared via terminal modification reactions. Then, PEG-2N3(-4Cl) was applied to initiate the a...

A branching point thermo and pH dual-responsive hyperbranched polymer based on poly(N-vinylcaprolactam) and poly(N,N-diethyl aminoethyl methacrylate)
We report the design and synthesis of a branching point stimuli-responsive hyperbranched polymer based on poly(N-vinylcaprolactam) and poly(N,N-diethylaminoethyl methacrylate) through combined“A2+BxC” (x > 2) double monomer polymerization and parallel click reaction. The results of ultraviolet-visible
spectrophotometry and dynamic light scattering (DLS) indicated that the resultant ...

Synthesis and thermally-triggered self-assembly behaviors of a dumbbell-shaped polymer carrying β-cyclodextrin at branch points
We report the design and synthesis of a thermally-responsive dumbbell-shaped polymer based on one β-cyclodextrin (β-CD)-terminated polyethylene glycol (PEG) segment and several poly(N-isopropylacrylamide) (PNIPAM) segments through combining click reaction with atom transfer radical polymerization. Thermally-triggered self-assembly and molecular inclusion behaviors of the polymer were i...

Gelation Originated from Growth of Wormlike "Living Polymer" of Symmetrically Dendronized Large-Ring Crown Ether in Dilute Solutions
The hierarchical pathway from homogeneous solution to gel of a large-ring crown ether
symmetrically substituted with four first-generation Percec-type dendrons (1) in n-dodecane has been followed by differential scanning calorimetry (DSC), small-angle X-ray scattering (SAXS), and fluorescence anisotropy methods. The 1/n-dodecane mixture requires a rather low gelation concentration of ～0...
