Novel global-like second-order nonlinear optical dendrimers: convenient synthesis through powerful click chemistry and large NLO effects achieved by using simple azo chromophore
关键字：second-order nonlinear optical dendrimers, click chemistry, azo chromophore
In this paper, global-like dendrimers, G1-TPA, G2-TPA and G3-TPA, bearing 9, 21 and 45 azobenzene chromophore moieties, respectively, 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 their perfect 3D structure and the isolation ...

Facile synthesis of soluble aromatic poly(amide amine)s via C–N coupling reaction: Characterization, thermal, and optical properties
关键字：aromatic poly(amide amine)s; high-performance
Aromatic poly(amide amine)s (APAAs), as novel highperformance polymers, have been obtained by the condensation polymerization of N,N’-bis(4-bromobenzoyl)-p-phenylenediamine with two different primary aromatic diamines via palladiumcatalyzed aryl amination reaction. The structures of the polymers are characterized by means of FTIR, 1H NMR spectroscopy, and elemental analysis, the results show a ...

Preparation and characterization of polyimide optical compensator used in liquid crystal display units(LCD)
关键字：polyimide, birefringent film, polyimide film, negative birefringence.
Two kinds of polyimides with side-group(-CH3) and their films have been produced. The polyimides produced were soluble in strong polar solvents such as NMP, DMAc and DMF. Compared with conventional polyimide films, the polyimide f...

【[Sensors and Actuators B: Chemical]】Interesting optical variations of the etching of Au Nanobipyramid@Ag Nanorods and its application as a colorful chromogenic substrate for immunoassays
Common colorimetric immunoassays only show monochromatic intensity variations, and the absorbance intensity is utilized for the quantitative detection of the analytes. Recently we have shown that gold nanorods and Au Nanobipyramids are good multicolor chromogenic substrates for immunoassays, and the LSPR peak shifts are used for the quantitative
detection of the analytes. Herein, we demonstra...
