(Chem.Eur.J.) Amphiphilic Diblock Copolymers Bearing a Cysteine Junction Group: Synthesis, Encapsulation of Inorganic Nanoparticles and Near Infrared Photoresponsive Properties
Encapsulation of inorganic nanoparticles (NPs) into the interfaces of amphiphilic vesicles is a challenging task. The traditional strategy is to use amphiphilic triblock copolymers, which possess two outer blocks for building the walls and coronas of vesicles, and one middle NP-binding block for localizing NPs at the vesicle interfaces. In this manuscript, we design and synthesize an amphiphilic d...

How does a tiny terminal alkynyl end group drive fully hydrophilic homopolymers to self-assemble into multicompartment vesicles and flower-like complex particles?
It is a theoretical and technical challenge to construct well-defined nanostructures such as vesicles from fully hydrophilic homopolymers in pure water. In this paper, we incorporate one terminal alkynyl group into a fully hydrophilic linear or non-linear homopolymer to drive its unusual self-assembly in aqueous solution to form multicompartment vesicles, spherical compound micelles...

[J. Am. Chem. Soc.] Rare Earth Metal-Mediated Group-Transfer Polymerization: From Defined Polymer Microstructures to High-Precision Nano-Scaled Objects
Poly(2-isopropenyl-2-oxazoline) (PIPOx) and poly(2-vinylpyridine) (P2VP) have been efficiently synthesized using bis(cyclopentadienyl)methylytterbium (Cp2YbMe) as catalyst. The polymerizations of 2-isopropenyl-2-oxazoline (IPOx) and 2-vinylpyridine (2VP) follow a living group-transfer polymerization (GTP) mechanism, allowing a precise molecular-weight control of both polymers with very narrow mo...

Syntheses and second-order nonlinear optical properties of a series of new “H”-shape polymers
关键字：Click chemistry, H-type chromophore, Nonlinear optics,Synthesis, Suzuki coupling copolymerization, Suitable isolation group
To develop more “H”-shape nonlinear optical polymers, in this paper, four new polymers embedded with “H”-type chromophore moieties were designed and synthesized through a Suzuki coupling copolymerization reaction. The “H”-type chromophores were easily prepared by the utilization of “Click Chemistry” reactions, and their structures could be conveniently adjusted by changing the diazido gr...

Second-order nonlinear optical dendrimers containing different types of isolation groups: convenient synthesisthrough powerful “click chemistry” and large NLO effects
关键字：Second-order nonlinear, click chemistry, isolation group
In this paper, two series of dendrimers, which contain normal phenyl or pentafluorophenyl as the endcapped group, were conveniently prepared with high purity and satisfactory yields, through the combination of divergent and convergent approaches, coupled with the utilization of the powerful Sharpless “click” reaction. Due to the Ar–ArF self-assembly effect, as well as their perfect 3D structu...

Attempt to Improve the Performance of Pyrrole-Containing Dyes in Dye Sensitized Solar Cells by Adjusting Isolation Groups
关键字：pyrrole, isolation group, “H” type dyes, organic sensitizer, dye-sensitized solar cell
Four new pyrrole-based organic sensitizers with different isolation groups were conveniently synthesized and applied to dye sensitized solar cells (DSCs). The introduction of isolation group in the side chain could both suppress the formation of dye aggregates and electron recombination. Especially, when two pieces of D-π-A chromophore moieties shared one isolation group to c...
