Photoenhanced gene transfection by a star-shaped polymer consisting of a porphyrin core and poly(L-lysine) dendron arms
A star-shaped polymer (PP-PLLD) consisting of a porphyrin (PP) core and poly(L-lysine) dendron
arms (PLLD) is synthesized by the click reaction, and its ability to deliver pEGFP is investigated
in this paper. It is found that PP-PLLD has a good buffer capacity and can form compact
complexes with pEGFP. In vitro assay indicates that PP-PLLD shows photoenhanced gene
transfection efficiency. PP-P...

Robust microsieves with excellent solvent resistance: cross-linkage of perforated polymer films with honeycomb structure
Polymeric microsieves with uniform and tunable pores were fabricated with the breath-figure method and sequent vulcanization procedure using commercially available block copolymer polystyrene-b-polyisoprene-b-polystyrene. Uniform pore size and small film thickness endow the microsieves with high size selectivity and low operation pressure, while the cross-linked chemical structure gives them goo...

[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

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...
