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...

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...

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...

Poly(9,9’-diheylfluorene carbazole) Functionalized with Reduced GrapheneOxide: Convenient Synthesis using Nitrogen-Based Nucleophiles and Potential Applications in Optical Limiting
关键字：graphene, nitrogencentered anions,nonlinear optics, nucleophilic addition, polymers
Covalently functionalized reduced graphene oxide (RGO) sheet was prepared by treating nitrogen-centered anions generated from poly(9,9’-diheylfluorene carbazole) (PCF) with
GO. The resultant hybrids with different chemical behavior were separated by centrifugation. The covalent modification was fully characterized by IR spectroscopy, UV/Vis spectroscopy, thermogravimetric analysis (TGA), Raman sp...
