Micelles endowed with multiple functionalities are very attractive in biomedical applications. We report in this paper a facile way to prepare novel amine-functionalized monomethoxy-poly(ethylene glycol)-b-poly(ε-caprolactone) (mPEG-b-PCL) amphiphilic block copolymers for the formulation of versatile micelles. In our synthetic route,monomethoxy-poly(ethylene glycol)-b-poly[ε-caprol...

The introduction of the Barbier reaction into polymer chemistry
The Barbier reaction, a widely utilized reaction for carbon–carbon bond formation, has played important roles in modern organic chemistry for more than a century. Here, we show its successful introduction to polymer chemistry. Through one-pot Barbier polyaddition (both A2+B2 type and AB type) of monomers containing an organic halide and a benzoyl group, a series of phenylmethanol group containi...

Reversible addition-fragmentation chain transfer (RAFT) polymerization is a more robust and versatile approach than other living free radical polymerization methods for synthesis of well-defined homo-, gradient, block, star-shaped and more complex structural polymers, like micro(nano)gels and polymer brushes. Thus the resultant polymers with thiocarbonylthio-terminated groups are readily tailored ...

A series of copolymers containing ε-caprolactone (CL) and 4-methyl-ε-cap-rolactone (MeCL) were synthesized by ring-opening polymerization (ROP) using Tin(Ⅱ)bis(2-ethylhexanoate)(Sn(Oct)2) or Novozym 435 as catalyst. The molecular structure and weight of copolymers were determined by Nuclear Magnetic Resonance (NMR) and size exclusion chromatography (SEC), respectively. Our kinetic...

A mild and efficient strategy is presented for growing thermo-sensitive polymers directly from the surface of exfoliated graphene oxide (GO). This method involves the covalent attachment of Br-containing initiating groups onto the surface of GO sheets followed by in situ growing poly[poly(ethylene glycol) ethyl ether methacrylate] (PPEGEEMA) via single-electron- transfer living radical polymerizat...

Graphene nanosheets offer intriguing electronic, thermal and mechanical properties and are expected to find a variety of applications in high-performance nanocomposite materials. The great challenge of exfoliating and dispersing pristine graphite or graphene sheets in various solvents or matrices can be achieved by facilely and properly chemical functionalization of the carbon nanosheets. Here we ...

Hydroxyl-functionalized three-arm poly(_-caprolactone)s (PGCL-OHs) were synthesized by the ring-opening polymerization of _-caprolactone in the presence of glycerol (as the core) and stannous octoate. The effect of the feed ratio of _-caprolactone to glycerol on the ring-opening polymerization was studied. These three-arm PGCL-OHs were then converted into double-bond-functionalized three-arm poly(...

ICOSAHEDRAL CARBORANES AS BUILDING BLOCKS IN POLYMER CHEMISTRY
Boron is a fascinating element that owes its name to the first ore discovered: borax from the Arabic buraq, meaning white. Having many interesting features, it is surprisingly one of the simplest elements in the periodic ...
