Photochemically controlled synthesis of anisotropic Au nanostructures : platelet-like Au nanorods and six-star Au nanoparticles

Huang, Xiao; Qi, Xiaoying; Huang, Yizhong; Li, Shaozhou; Xue, Can; Gan, Chee Lip; Boey, Freddy Yin Chiang; Zhang, Hua (2010)

We report the shape-controlled synthesis of anisotropic Au nanostructures through TiO2-assisted photochemical reduction of HAuCl4. By using this method, we have successfully synthesized the platelet-like Au nanorods and ...

Amphiphilic graphene composites

Qi, Xiaoying; Pu, Kan-Yi; Li, Hai; Zhou, Xiaozhu; Wu, Shixin; Fan, Qu-Li; Liu, Bin; Boey, Freddy Yin Chiang; Huang, Wei; Zhang, Hua (2010)

Both kinds of solubility: An amphiphilic reduced graphene oxide (rGO) composite is synthesized by using a novel coil-rod-coil conjugated triblock copolymer as the π–π binding stabilizer. Such a graphene-based composite can ...

Reduced graphene oxide-templated photochemical synthesis and in situ assembly of Au nanodots to orderly patterned Au nanodot chains

Huang, Xiao; Zhou, Xiaozhu; Wu, Shixin; Wei, Yanyan; Qi, Xiaoying; Zhang, Juan; Boey, Freddy Yin Chiang; Zhang, Hua (2010)

A novel photochemical method for the synthesis of fluorescent Au nanodots (size ≈1.2nm) is proposed (see image). The results clearly demonstrate that reduced graphene oxide sheets modified with functional organic molecules ...

In situ modification of three-dimensional polyphenylene dendrimer-templated CuO rice-shaped architectures with electron beam irradiation

Qi, Xiaoying; Huang, Yizhong; Klapper, Markus; Boey, Freddy Yin Chiang; Huang, Wei; Feyter, Steven De; Müllen, Klaus; Zhang, Hua (2010)

In this study, the high-energy electron beam of the transmission electron microscope (TEM) is utilized as an external force to in situ modify the polyphenylene dendrimer (G2Td(COOH)16) templated CuO rice-shaped architecture ...

Conjugated-polyelectrolyte-functionalized reduced graphene oxide with excellent solubility and stability in polar solvents

Qi, Xiaoying; Pu, Kan-Yi; Zhou, Xiaozhu; Li, Hai; Liu, Bin; Boey, Freddy Yin Chiang; Huang, Wei; Zhang, Hua (2010)

Conjugated-polyelectrolyte (CPE)-functionalized reduced graphene oxide (rGO) sheets are synthesized for the first time by taking advantage of a specially designed CPE, PFVSO3, with a planar backbone and charged sulfonate ...

Polyphenylene dendrimer-templated in situ construction of inorganic–organic hybrid rice-shaped architectures

Qi, Xiaoying; Xue, Can; Huang, Xiao; Huang, Yizhong; Zhou, Xiaozhu; Li, Hai; Liu, Daojun; Boey, Freddy Yin Chiang; Yan, Qingyu; Huang, Wei; De Feyter, Steven; Müllen, Klaus; Zhang, Hua (2010)

A novel dendrimer-templating method for the synthesis of CuO nanoparticles and the in situ construction of ordered inorganic–organic CuO–G2Td(COOH)16rice-shaped architectures (RSAs) with analogous monocrystalline structures ...
