In-situ formation of biodegradable hydrogels by stereocomplexation of PEG-(PLLA)(8) and PEG-(PDLA)(8) star block copolymers
Eight-arm poly( ethylene glycol)-poly(L-lactide), PEG-(PLLA)(8), and poly(ethylene glycol)-poly(D-lactide), PEG(PDLA)(8), star block copolymers were synthesized by ring-opening polymerization of either L-lactide or D-lactide at room temperature in the presence of a single-site ethylzinc complex and 8-arm PEG (M-n = 21.8 x 10(3) or 43.5 x 10(3)) as a catalyst and initiator, respectively. High lacti...

荧光性高分子的可控合成
关键字：fluorescence star-shaped dendrimer-like copolymer core-shell micelles
Novel and well-defined pyrene-containing eight-arm star-shaped dendrimer-like copolymers (PSt-b-(PCL-pyrene)2)4 were successfully achieved. Fluorescence analysis indicated that (PSt-b-(PCL-pyrene)2)4 presented slightly stronger fluorescence intensity than 1-pyrenebutyric acid&nbs...

(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...
