Using Two Simple Methods of Ar-ArF Self-Assembly and Isolation Chromophores to Further Improve the Comprehensive Performance of NLO Dendrimers**
关键字：isolation chromophores, click chemistry, dendrimers, nonlinear optics, self-assembly
Herein, through a combination of divergent and convergent approaches, coupled with the utilization of the powerful Sharpless “click chemistry” reaction, two series of high-generation nonlinear optical (NLO) dendrimers have been conveniently prepared in high purity and satisfactory yields. Perfluoroaromatic rings and isolation chromophores were intro...

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...

Electrochemical Performance of Lithium Ion Capacitors Using Li+-Intercalated Mesocarbon Microbeads as the Negative Electrode
关键字：Lithium ion capacitor; Hybrid capacitor; Mesocarbon microbead; Activated carbon; Li pre-doping
Lithium ion capacitors (LICs) were fabricated using Li+-intercalated mesocarbon microbeads(LMCMBs) as the negative electrode and commercial activated carbon (AC) as the positive electrode. The phase structure of LMCMB electrodes was characterized by X-ray diffraction (XRD). LMCMB electrodes retain their original graphite crystal structure when the capacity induced by initial L...

Preparation and Surface-enhanced Raman Performance of Electrospun Poly(vinyl alcohol)/ high-concentrationgold Nanofibers
关键字：Gold nanoparticles，Poly (vinyl alcohol)，Electrospinning，Surface-enhance Raman scattering
A facile approach to prepare electrospun poly(vinly alcohol) (PVA) nanofibers with high concentration of gold nanoparticles (Au NPs) on the fibers, had been developed. These PVA/Au nanofibers could be used as flexible surface-enhanced Raman scattering (SERS) substrates. Relatively high concentration of PVA aqueous solution (10 wt %) was used as the stabilizing agent for gold salt precursor, as wel...
