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...

High-Generation Second-Order Nonlinear Optical (NLO) Dendrimers that Contain Isolation Chromophores: Convenient Synthesis by Using Click Chemistry and their Increased NLO Effects
关键字：azo compounds, chromophores, click chemistry, dendrimers, nonlinear optics
Herein, high-generation dendrimers G4-NS and G5-NS, which contained 30 and 62 azo-benzene chromophore moieties, respectively, were conveniently prepared in high purity and satisfied yields by a combination of divergent and convergent approaches, coupled with the utilization of the powerful Sharpless click reaction. These dendrimers possessed a regular structure of alternating layers of nitro-based...

Novel perfluorocyclobutyl (PFCB)-containing polymers formed by click chemistry
关键字：Poly(alkyl aryl) ethers, Perfluorocyclobutane (PFCB), Click chemistry
The synthesis and characterization of a novel class of linear poly(alkyl aryl) ethers containing 1,2,3-triazolyl and perfluorocyclobutyl units have been described. These polymers were readily prepared from the Huisgen’s 1,3-dipolar cycloaddition of poly(ethylene glycol) diazides and 1,2-bis(4-ethynylphenoxy)perfluorocyclobutane that is defined as ‘click chemistry’ recently....

关键字：copolymerization, reactivity ratios, chain sequence, crystallization
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...

关键字：ATRP /PCL/PDEAEMA /pH sensitivity/ ROP/self-assembly
Four-arm star block polymers consisting of hydrophobic poly(ε-caprolactone) (PCL) block and hydrophilic poly(2-(diethylamino) ethyl methacrylate)) (PDEAEMA) block were successfully synthesized by ring opening polymerization (ROP) and atom transfer radical polymerization (ATRP). Chain lengths of PDEAEMA segments were varied to obtain a series of star copolymers with different hydrophilic/hy...
