(Macromol. Rapid Commun)Controlling CO2-Responsive Behaviors of Polymersomes Self-Assembled by Coumarin-Containing Star Polymer via Regulating Its Crosslinking Pattern
An oligo(ethylene glycol)-based star polymer of N2-(OEG-C)3 with fluorescent coumarin as hydrophobic end groups and dual tertiary amines as the star center is designed and synthesized. Owing to its amphiphilic nature of N2-(OEG-C)3, it will self-assemble into hollow vesicles with coumarin groups dispersed in the hydrophobic membrane and exhibits CO2-responsive behavior due to the protonation of ...

Novel ‘‘star anise’’-like nano aggregate prepared by self-assembling of preformed microcrystals from branched crystalline-coil alternating multi-block copolymer
Nano aggregates in aqueous medium with a novel ‘‘star anise’’-like morphology were prepared from a branched alternating multiblock copolymer composed of 3-arm star-like hydrophobic poly(p-dioxanone) block and linear hydrophilic poly(ethylene glycol) block. The influence of block length on the morphology of the nano aggregate was investigated.

Facile Synthesis of Hydroxyl-Ended, Highly Stereoregular, Star-Shaped Poly(lactide) from Immortal ROP of rac-Lactide and Kinetics Study
Triethanolamine
(TEA) reacted with 3 equiv of yttrium alkyl complex 1 bearing
O,N,N,Otetradentate Salan ligand to give a trinuclear yttrium alkoxide
counterpart 2 via metathesis reaction. Complex 2 initiated the ring-opening
polymerization of rac-lactide in a livingness mode under mild conditions. Remarkably,
2 was so tolerant of the protic TEA that under various TEA-to-yttrium molar
ratios rang...

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...

[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...

Synthesis of an amphiphilic PEG-PCL-PSt-PLLA-PAA star quintopolymer and its self-assembly for pH-sensitive drug delivery
http://pubs.rsc.org/en/content/articlelanding/2014/py/c3py01601c#!divAbstract
The synthesis and properties of a star quintopolymer comprising poly(ethylene glycol) (PEG, A), poly(ε-caprolactone) (PCL, B), polystyrene (PSt, C), poly(L-lactide) (PLLA, D), and poly(acrylic acid) (PAA, E) segments were described. Terminal diazide functionalized PEG (PEG-(N3)2), alkyne-mid-functionalize...

Star-shaped polymer consisting of a porphyrin core and poly(L-lysine) dendron arms: synthesis, drug delivery and in vitro chemo/photodynamic therapy
A novel star-shaped polymer, porphyrin-poly(L-lysine) dendrons (PP-PLLD), is synthesized by
the click reaction between azido-modifi ed porphyrin and propargyl focal point poly(L-lysine)
dendrons. Its chemical structure is characterized by 1 H nuclear magnetic resonance, Fourier
transform infrared spectroscopy, and gel permeation chromatography (GPC) is analyses etc.
Due to its amphiphilic prop...

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. 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...
