      Multicomponent nanoparticles can be synthesized in high-temperature organic phases. A variety of morphologies such as core/shell, binary heterodimer, nano-dumbbell, and ternary nanostructures have been obtained. The nanostructures synergistically combine magnetic, plasmonic, and semiconducting properties, and may have unique applications.

    1. Fine-Tuning of Yellow or Red Photo- and Electroluminescence of Functional Difluoro-boradiazaindacene Films (pages 401–413)

      Laure Bonardi, Hani Kanaan, Franck Camerel, Pascale Jolinat, Pascal Retailleau and Raymond Ziessel

      Color tuning. Doping Alq3 films with trimethoxyphenyl-difluoro-boradiazaindacene derivatives by vacuum evaporation produces organic light-emitting diodes that emit yellow or red light depending on the degree of doping. The yellow light is due to well-dispersed monomers whereas the red light is due to emission of dimerized molecules.

    2. Functionalizing Carbon Nanotubes by Grafting on Intumescent Flame Retardant: Nanocomposite Synthesis, Morphology, Rheology, and Flammability (pages 414–421)

      Hai-Yun Ma, Li-Fang Tong, Zhong-Bin Xu and Zheng-Ping Fang

      Version of Record online: 30 JAN 2008 | DOI: 10.1002/adfm.200700677

      An intumescent flame retardant, PDSPB has been covalently grafted onto the surfaces of multiwalled carbon nanotubes (MWNTs). The combination of PDSPB and MWNTs can improve both the dispersion of nanotubes in the polymer matrix and the flame retardancy of the nanocomposites.

    3. Nanocarving of Titania as a Diffusion-Driven Morphological Instability (pages 422–431)

      Doh-Kwon Lee and Juergen Janek

      Version of Record online: 30 JAN 2008 | DOI: 10.1002/adfm.200601189

      Thumbnail image of graphical abstract

      A nanometer-scale and periodic microstructure of titania develops at the low P(O2) surface with (001) orientation upon chemical reduction in an oxygen activity gradient. A diffusion-driven morphological instability combined with a diffusion anisotropy is proposed as a semi-quantitative model to describe the kinetics of the process.

    4. Structural, Electrical, and Thermal Behavior of Graphite-Polyaniline Composites with Increased Crystallinity (pages 432–440)

      Shawn Bourdo, Zhongrui Li, Alexandru S. Biris, Fumiya Watanabe, Tito Viswanathan and Ioana Pavel

      Thumbnail image of graphical abstract

      The correlation between the structural, electrical, and thermal behavior of graphite-polyaniline (G-PANI 1-5) composites with electrical conductivities greater than either of the individual components (see figure) is investigated. The structural changes related to this increase in electrical conductivity are clearly evidenced by Raman spectra and XRD data, which indicate improved crystallinity through better stacking along the c-axis of graphite and a slight increase in the (002) graphite crystal plane distance when PANI is present.

    5. Electrospun Palladium Nanoparticle-Loaded Carbon Nanofibers and Their Electrocatalytic Activities towards Hydrogen Peroxide and NADH (pages 441–448)

      Jianshe Huang, Dawei Wang, Haoqing Hou and Tianyan You

      Palladium nanoparticle-loaded carbon nanofibers (Pd/CNFs) are synthesized by a combination of electrospinning and thermal treatment processes (see figure). This nanocomposite material possesses a large electroactive surface area, and exhibits high electrocatalytic activities towards the reduction of H2O2 and the oxidation of NADH.

    6. Photosensitive Carbon Nanotube Paste Based on Acrylated Single-Walled Carbon Nanotubes (pages 449–454)

      Myung-Sup Jung, Jingyu Hyeon-Lee, Jeong-Hee Lee, Jong-Jin Park, In-Sun Jung and Jong-Min Kim

      Thumbnail image of graphical abstract

      A photosensitive carbon nanotube (CNT) paste based on an acrylated single walled carbon nanotube, a cross-linking agent, and a photoinitiator is prepared. After UV exposure and development with N,N-dimethylformamide, a pattern with a resolution of 8 µm is obtained from the photosensitive CNT paste, which is then fired at 300°C to give a clear CNT pattern.

    7. The Effect of Morphological Modification on the Electrochemical Properties of SnO2 Nanomaterials (pages 455–461)

      Min-Sik Park, Yong-Mook Kang, Gou-Xiu Wang, Shi-Xue Dou and Hua-Kun Liu

      Version of Record online: 30 JAN 2008 | DOI: 10.1002/adfm.200700407

      Thumbnail image of graphical abstract

      The electrochemical performance of 1D SnO2 nanomaterials (nanotubes, nanowires, and nanopowders) can be used to define the most favorable morphology when SnO2 nanomaterials are adopted as the electrode material for lithium-ion batteries. Changes in the morphology of SnO2 (see figure) are found to be closely related to the electrochemical performance.

      On the basis of a quantum-chemical description of the lowest singlet electronic excited states of bi-chromophoric model systems, we have disentangled the through-bond (TB) from the through-space (TS) contributions to the electronic interactions mediating energy hopping in rigid-rod conjugated polymers.

      Tuning the emission color in IrIII-based triplet emitters (Ir-X, see figure) using electron-withdrawing main-group moieties is described for the first time. This new color tuning strategy also provides access to IrIII phosphors with improved electron injection/electron transporting features, essential for highly efficient, multicolor OLEDs.
