      Vertically aligned SWNTs (v-SWNTs) have been successfully prepared by using chemical assembly strategy. We summarize the various approaches for the preparation of v-SWNTs using chemical assembly techniques, discuss the characterization, assembly kinetics, and charge transfer properties of v-SWNTs. We also review the applications of v-SWNTs in many fields, including electrochemical and bioelectrochemical sensors, photoelectric conversion, and scanning probe microscopy.

    1. Homogeneously Dispersed Ceria Nanocatalyst Stabilized with Ordered Mesoporous Alumina (pages 1475–1478)

      Version of Record online: 22 FEB 2010 | DOI: 10.1002/adma.200904223

      Homogeneously dispersed ceria nanocatalyst can be synthesized and stabilized with ordered mesoporous alumina by a one-step sol–gel method. This novel material possesses high thermal stability and exhibits 100% conversion at room temperature for CO oxidation when loaded with Au. This established approach can be expanded to the controlled synthesis and stabilization of other nanocatalysts with wide applications.

      Jiefeng Yu, Yu Wang, Wen Wen, Donghan Yang, Bin Huang, Jianlong Li and Kai Wu

      Version of Record online: 4 MAR 2010 | DOI: 10.1002/adma.200903656

      Thumbnail image of graphical abstract

      An aluminothermal reaction approach is used for the reaction between Al powder and other metal oxide(s) in a chemical vapor deposition furnace to generate a pressure burst of the intermediate vapor that subsequently condenses or reacts with gases to form micro-/nanomaterials on a substrate.

    3. High-Performance Organic Field-Effect Transistors from Organic Single-Crystal Microribbons Formed by a Solution Process (pages 1484–1487)

      Yan Zhou, Ting Lei, Lei Wang, Jian Pei, Yong Cao and Jian Wang

      Version of Record online: 8 MAR 2010 | DOI: 10.1002/adma.200904171

      Thumbnail image of graphical abstract

      High performance p-channel transistors based on a single-crystal organic microribbon self-assembled through a solution process, are achieved by enhancing the crystallinity, improving the interface between the dielectric and the crystal, shrinking the channel length, and realizing asymmetric metal electrodes for source and drain (see figure). The highest mobility reached is 2.1 cm2 V−1 s−1 with an on/off ratio of 2 × 105 and a threshold voltage of −7 V.

    4. pH-Sensitive Water-Soluble Nanospheric Imprinted Hydrogels Prepared as Horseradish Peroxidase Mimetic Enzymes (pages 1488–1492)

      Zhiyong Chen, Li Xu, Yuan Liang and Meiping Zhao

      Version of Record online: 28 DEC 2009 | DOI: 10.1002/adma.200903122

      Thumbnail image of graphical abstract

      Water-soluble hydrogel nanoparticles have been synthesized by the incorporation of the stimuli-sensitive monomer of N-isopropylacrylamide (NIPAM) to a catalytic, molecularly imprinted system. The unique properties of pNIPAM copolymerized with cationic and anionic polymers offers a homogenously biocompatible catalytic system with switchable response to pH change. The maximum catalytic efficiency can thus be significantly increased.

    1. Colloidal-Crystal-Assisted Patterning of Crystalline Materials (pages 1494–1497)

      Cheng Li and Limin Qi

      Version of Record online: 1 FEB 2010 | DOI: 10.1002/adma.200903044

      Thumbnail image of graphical abstract

      Patterned micro- and nanostructures with complex architectures have been constructed with the aid of colloidal crystals as versatile templates. This article highlights some recent progress in the patterning of crystalline materials assisted by colloidal crystals under ambient conditions. Unique 3DOM calcite single crystals are fabricated via a transient amorphous phase in combination with a colloidal-crystal templating method (see figure).

    2. Preparation of Open-Cage Fullerenes and Incorporation of Small Molecules Through Their Orifices (pages 1498–1507)

      Liangbing Gan, Dazhi Yang, Qianyan Zhang and Huan Huang

      Version of Record online: 8 FEB 2010 | DOI: 10.1002/adma.200903705

      Thumbnail image of graphical abstract

      Endohedral fullerenes, such as the fullerene enclosing a water molecule shown schematically in the figure, are formed when open-cage fullerenes act as hosts for small molecules. Methods of creating a hole in the fullerene surface are surveyed, and insertion of molecules such as water, hydrogen, nitrogen, and methane is described.

    3. How Catalysts Affect the Growth of Single-Walled Carbon Nanotubes on Substrates (pages 1508–1515)

      Yan Li, Rongli Cui, Lei Ding, Yu Liu, Weiwei Zhou, Yan Zhang, Zhong Jin, Fei Peng and Jie Liu

      Version of Record online: 5 MAR 2010 | DOI: 10.1002/adma.200904366

      Thumbnail image of graphical abstract

      The structure of SWNTs highly depends on the property of catalysts. The controlled preparation and patterning of catalyst nanoparticles on substrates and the growth of SWNTs are discussed. Some new catalysts are found, among which Cu and Pb are superior for preparing SWNTs on substrates for building nanodevices. The study also offers more hints for understanding the growth mechanism of SWNTs (see figure).

    4. Soft Template Synthesis of Yolk/Silica Shell particles (pages 1516–1520)

      Xue-Jun Wu and Dongsheng Xu

      Version of Record online: 12 FEB 2010 | DOI: 10.1002/adma.200903879

      Thumbnail image of graphical abstract

      A mixture of anionic and zwitterionic surfactants was used as soft templates for the preparation of yolk/silica shell particles. Moreover, it is demonstrated that yolk/mesoporous silica shell particles and multishelled particles can be synthesized by this strategy (see figure).

    5. Solvent-Stabilized Photoconductive Metal Phthalocyanine Nanoparticles: Preparation and Application in Single-Layered Photoreceptors (pages 1521–1525)

      Yuan Wang and Dejian Liang

      Version of Record online: 1 FEB 2010 | DOI: 10.1002/adma.200903120

      Thumbnail image of graphical abstract

      Solvent-stabilized photoconductive nanoparticles of phthalocyanines are promising building blocks for the fabrication of photoelectric devices (see figure; PCM = photoconductive material). The high stability of these colloidal nanoparticles in C2H4Cl2 is attributed to a solvation effect and the electrostatic repulsion between the particles. Single-layered photoreceptors constructed by dispersing oxovanadium phthalocyanine or oxotitanium phthalocyanine nanoparticles in films of polycarbonate resins exhibit excellent xerographic properties in the positively charged model.

    6. Formate-Based Magnetic Metal–Organic Frameworks Templated by Protonated Amines (pages 1526–1533)

      Zheming Wang, Keli Hu, Song Gao and Hayao Kobayashi

      Version of Record online: 26 MAR 2010 | DOI: 10.1002/adma.200904438

      Thumbnail image of graphical abstract

      A study of the 3d divalent metal formates, templated by protonated amines, has created chiral (49 · 66), perovskite (412 · 63), bi-nodal (412 · 63)(49 · 66)n (n = 1 to 3), and diamond 66 metal formate frameworks, depending on the templates used. These materials display various magnetic, dielectric, porous, and optical properties, and combinations thereof. It is expected that the more or less ignored formate will play an important role in the study of molecule-based materials.

    7. Functional IrIII Complexes and Their Applications (pages 1534–1539)

      Zhu-qi Chen, Zu-qiang Bian and Chun-hui Huang

      Version of Record online: 9 FEB 2010 | DOI: 10.1002/adma.200903233

      Thumbnail image of graphical abstract

      The molecular design of suitable ligands for iridium complexes receives a lot of attention because Ir complexes exhibit high phosphorescence quantum efficiencies. To achieve phosphorescent emission over a wide range of wavelengths, the structure of the complexes has to be engineered so that they are compatible with many applications (see figure). In this article, we focus on the use of materials design to improve the performance of phosphorescent Ir(III) complexes for OLEDs, luminescence sensitizers, and biological imaging.
