High optical transparency and low dielectric constant of organosoluble polyamide based on 1, 2-Bis-(4-amino-2-trifluoromethylphenoxy) benzene
关键字：trifluoromethyl group,polyamide,solubility,dielectric constant
A novel fluorinated polyamide was prepared from an aromatic diamine containing trifluoromethyl group (–CF3), 1,2-bis(4-amino-2-trifluoromethylphenoxy)benzene, and aromatic dicarboxylic acids(OBA) by using phosphorylation polycondensation. The fluorinated polyamide was&...

Acetylenes with multiple triple bonds: a group of versatile An-type building blocks for the construction of functional hyperbranched polymers
关键字：Acetylene polymerization; Hyperbranched polymers; Functional materials
ABn-type molecules are widely used as monomers for the synthesis of hyperbranched polymers. Because the mutually reactive A and B groups are liable to self-oligomerize, the monomers are difficult to prepare and handle. We have&nbs...

(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...
