      Highly active novel three dimensional cubic Fm3m mesoporous aluminosilicates (AlKIT-5) with very high structural order and unprecedented loadings of Al have been successfully prepared. The catalytic activity in the acetylation of veratrole of the AlKIT-5 catalysts is found to be superior over mordenite, zeolite H-Y, zeolite H-β, and ZSM-5.

      Triantennary, gallactoside-capped gallamide dendron with a thiolate focal group is anchored onto the surface of CdSe/ZnS core/shell nanoparticle. The nanohybrid can be delivered selectively inside asialoprotein receptor-enriched lung cancer cells without cell damage, a potential photodynamic drug carrier for apoptosis.

      Hierarchical silica nanotubes with radially oriented mesoporous channels, with different average inner diameter, wall thickness and with a similar mesopore size of ∼4 nm were synthesized based on the re-assembly of lipid nanotubes, co-structure directing agent and inorganic silica precursor.

    3. Facile Formation of Uniform Shell-Crosslinked Nanoparticles with Built-in Functionalities from N-Hydroxysuccinimide-Activated Amphiphilic Block Copolymers (pages 551–559)

      Yali Li, Isamu Akiba, Simon Harrisson and Karen L. Wooley

      The preparation of NAS-containing amphiphilic block copolymers allowed for their functionalization, assembly into micelles and crosslinking in situ. SAXS data quantitatively determined shell contraction and densification upon crosslinking.

    4. Room-Temperature Self-Organizing Characteristics of Soluble Acene Field-Effect Transistors (pages 560–565)

      Wi Hyoung Lee, Jung Ah Lim, Do Hwan Kim, Jeong Ho Cho, Yunseok Jang, Yong Hoon Kim, Jeong In Han and Kilwon Cho

      Thumbnail image of graphical abstract

      Spontaneous self-organization at room temperature induces dramatic changes in the morphology of triethylsilylethynyl-anthradithiophene films over a couple of days. The field-effect mobility of field-effect transistors based on these films increases about 100-fold after 7 days as a result of the change of molecular orientation from a tilted structure in the as-prepared film to a well-oriented structure in the final film (see figure)

    5. Organic Nanoclusters on Inorganic Nanostructures for Tailoring the Emission Properties of Organic Materials (pages 566–574)

      A series of bipolar host molecules (see figure) are developed based on theoretical DFT calculations and employed to fabricate phosphorescent OLEDs. The devices exhibit a best performance of 47 500 cd m−2 and 27.3 cd A−1 for spin-coated DM-TIBN, illustrating a new concept of localizing the HOMO and LUMO and a facile strategy to tailor the energy levels for bipolar molecules.

      Atomic layer deposition (ALD) of UV-absorbing ZnO on particles was performed in a fluidized bed reactor. Films were successfully deposited on bulk quantities of primary nanoparticles, ZnO particle ALD can functionalize particles to fabricate novel sunblocking composite materials.

    11. Magnetic Properties of Ni/NiO Nanowires Deposited onto CNT/Pt Nanocomposites (pages 616–621)

      Verónica Salgueiriño-Maceira, Miguel A. Correa-Duarte, Manuel Bañobre-López, Marek Grzelczak, Michael Farle, Luis M. Liz-Marzán and José Rivas

      Version of Record online: 4 FEB 2008 | DOI: 10.1002/adfm.200700846

      Thumbnail image of graphical abstract

      Ni/NiO-coated carbon nanotube/Pt nanocomposites show a blocked-state behavior even at room temperature. This is a consequence of the properties of the individual constituents (Ni/NiO nanocrystals), the morphology they have acquired (anisotropic nanowires), and the complex magnetic interactions between them (collective spin-glass-like behavior).

    12. Hybrid Solar Cells from a Blend of Poly(3-hexylthiophene) and Ligand-Capped TiO2 Nanorods (pages 622–633)

      Johann Bouclé, Sabina Chyla, Milo S. P. Shaffer, James R. Durrant, Donal D. C. Bradley and Jenny Nelson

      Thumbnail image of graphical abstract

      Hybrid blend solar cells based on ligand-capped TiO2 nanorods and poly-(3-hexylthiophene) (P3HT) are processed from solution for different blend compositions and particle surface ligands. Efficient charge-separation yields are achieved by replacing insulating surface ligands with an amphiphilic dye. However, photovoltaic device performance remains limited mainly by charge transport and trapping.

      Novel silver doped phosphate glasses, such as that shown in the figure, have demonstrated great promise in the field of biomaterials for their unique dissolution and antibacterial properties. These properties are investigated in terms of the material's structure using the advanced probe techniques of neutron diffraction with isotopic substitution and X-ray absorption spectroscopy.

    15. A Thermoresponsive Membrane for Chiral Resolution (pages 652–663)

      Mei Yang, Liang-Yin Chu, Hai-Dong Wang, Rui Xie, Hang Song and Catherine Hui Niu

      Version of Record online: 28 FEB 2008 | DOI: 10.1002/adfm.200700534

      Thumbnail image of graphical abstract

      Thermoresponsive gating membranes composed of functional gates with grafted thermoresponsive poly(N-isopropylacrylamide) (PNIPAM) chains and appended β-cyclodextrin (β-CD) moieties are a novel route to “smart”, efficient chiral resolution. With the cooperative function of β-CD's chiral recognition and PNIPAM's thermoresponsiveness, high, selective chiral resolution and efficient membrane regeneration are achieved by simply controlling the temperature (see figure; LCST: lower critical solution temperature).
