Hydrogen Storage in Microporous Hypercrosslinked Organic Polymer Networks
Hypercrosslinked polymer networks were synthesized by the self-condensation of bischloromethyl monomers such as dichloroxylene (DCX), 4,4'-bis(chloromethyl)-1,1'-biphenyl (BCMBP), and 9,10-bis(chloromethyl)anthracene (BCMA). These materials are predominantly microporous and exhibit BrunauerEmmett-Teller (BET) surface areas of up to 1904 m2/g as measured by N2 adsorption at 77.3 K (Langmuir s...

Dewetting and phase behaviors for ultrathin films of polymer blend.
Dynamics of dewetting and phase separation in ultrathin films (thickness is ca. one radius of gyration, ~ 1 Rg) of poly(methyl methacrylate) (PMMA) and poly(styreneran-acrylonitrile) (SAN) blends on Si substrate has been studied by in situ atomic force microscopy (AFM). In the miscible region, a ‘‘spinodal-like’’ dewetting driven by a composition fluctuation recently predic...

Imaging of elemental distribution at polymer interfaces for studies of adhesion.
The adhesion and fracture of styrene-acrylonitrile random copolymer and poly(methyl methacrylate) (PMMA/SAN) laminates were studied. They showed a drastic transition from brittle to ductile on varying the acrylonitrile (AN) content in SAN, with changes in the fracture mode from interfacial failure to cohesive fracture. Energy-filtering transmission electron microscopy (EFTEM) and scanning electron...

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 ...

New Hyperbranched Polytriazoles Containing Isolation Chromophore Moieties Derived from AB4 Monomers through Click Chemistry underCopper(I) Catalysis: Improved Optical Transparency and Enhanced NLOEffects
关键字：chromophores, click chemistry, hyperbranched polymers, isolation chromophores, nonlinear optics, polymers
By modifying a synthetic procedure, two new hyperbranched polytriazoles (HP1 and HP2) containing isolation chromophores were synthesized successfully through click chemistry reactions under copper(I) catalysis. For the first time, these two polymers were derived from an AB4-type monomer, although they contain different end-capping chromophores. They are soluble in normal polar organic solvents a...
