      Front Cover: Ordered poly(3-hexylthiophene)(P3HT) nanowires grow from carbon nanotube (CNT) surfaces through a bottom-up CNT-induced P3HT crystallization strategy. The cover picture schematically illustrates such a process with a TEM image showing P3HT nanowires on a multiwalled CNT. Further details can be found in the article by J. Liu, J. Zou, and L. Zhai*on page 1387.

    1. Simultaneous Chain-Growth and Step-Growth Polymerization—A New Route to Cyclic Polymers (pages 1371–1381)

      Depending on reaction conditions and catalysts cyclic and vinyl monomers may polymerize via a chain-growth process yielding difunctional chains with one reactive “a” and one “b” endgroup. Simultaneous condensation (or addition) reactions yield, in turn, longer chains and finally cyclic polymers.

    1. Rapid Formation of Acrylated Microstructures by Microwave-Induced Thermal Crosslinking (pages 1382–1386)

      Version of Record online: 22 JUN 2009 | DOI: 10.1002/marc.200900199

      Poly(ethylene glycol)-based polymeric microarray was synthesized by using microwave-induced thermal crosslinking without exogenous radical initiator in air. The advantages of this process make it a potentially useful method for fabricating polymeric microstructures for a wide range of applications.

    2. Bottom-up Assembly of Poly(3-hexylthiophene) on Carbon Nanotubes: 2D Building Blocks for Nanoscale Circuits (pages 1387–1391)

      Jianhua Liu, Jianhua Zou and Lei Zhai

      Version of Record online: 2 JUN 2009 | DOI: 10.1002/marc.200900225

      Hierarchical poly(3-hexylthiophene) (P3HT)/carbon nanotube (CNT) supramolecular structures were fabricated through a bottom-up CNT induced P3HT crystallization strategy. P3HT nanowires growing perpendicular from CNT surface have uniform width and height.

    3. Synthesis of Comb Tri- and Tetrablock Copolymers Catalyzed by the Grubbs First Generation Catalyst (pages 1392–1398)

      M. Brett Runge, Jun Yoo and Ned B. Bowden

      Version of Record online: 15 JUN 2009 | DOI: 10.1002/marc.200900146

      Exo-oxanorbornene monomers were polymerized with the Grubbs first generation catalyst to yield tri- and tetrablock copolymers with degrees of polymerization up to 1 100 and molecular weights of several hundred thousand grams per mole. Complex architectures were synthesized by the growth of polystyrene arms from selected blocks to yield comb block copolymers that assembled in the solid state into ordered morphologies.

    4. Poly(p-phenylene ethynylene) Incorporating Sterically Enshrouding m-Terphenyl Oxacyclophane Canopies (pages 1399–1405)

      Brad P. Morgan, Robert J. Gilliard Jr., Rahul S. Loungani and Rhett C. Smith

      Version of Record online: 22 JUN 2009 | DOI: 10.1002/marc.200900160

      Thumbnail image of graphical abstract

      Novel canopies comprised by m-terphenyl oxacyclophane units have been installed about a π-conjugated polymers backbone to shield one side of the π-system from interchain interactions and to scaffold π-stacking between the polymer and a canopy aryl ring. The canopy allowed for an enhanced kinetic response to vapors of explosives and explosive simulant nitroorganics such as TNT due to enhanced permeability.

    5. Dry Spinning Based Spinneret Based Tunable Engineered Parameters (STEP) Technique for Controlled and Aligned Deposition of Polymeric Nanofibers (pages 1406–1412)

      Amrinder S. Nain, Metin Sitti, Annette Jacobson, Tomasz Kowalewski and Cristina Amon

      Version of Record online: 2 JUN 2009 | DOI: 10.1002/marc.200900204

      Dry Spinning based nanomanufacturing platform encompassing automation and material rheological parameters is used for fabricating and depositing continuous and uniform diameter (defect-free) polymeric nanofiber arrays having diameters ranging from 50 to 500 nm and several millimeters in length in single and multiple layers.

    6. Synthesis of Well-Defined Polybenzamide-block-Polystyrene by Combination of Chain-Growth Condensation Polymerization and RAFT Polymerization (pages 1413–1418)

      Tomohiro Masukawa, Akihiro Yokoyama and Tsutomu Yokozawa

      Version of Record online: 15 JUN 2009 | DOI: 10.1002/marc.200900150

      Thumbnail image of graphical abstract

      Diblock copolymers composed of poly- (N-octylbenzamide) and polystyrene were synthesized by reversible addition- fragmentation chain transfer (RAFT) poly- merization of styrene with a polyamide chain transfer agent (CTA). Chain-growth condensation polymerization afforded poly(N-octylbenzamide), and introduction of a benzyl dithiocarbonyl group gave the polyamide-CTA. RAFT polymerization of styrene with this macro-CTA afforded well-defined poly(N-octylbenzamide)-block-polystyrene.

    7. Stepwise Self-Assembly of P3HT/CdSe Hybrid Nanowires with Enhanced Photoconductivity (pages 1419–1423)

      Jingjing Xu, Jianchen Hu, Xinfeng Liu, Xiaohui Qiu and Zhixiang Wei

      Version of Record online: 2 JUN 2009 | DOI: 10.1002/marc.200900132

      A stepwise self-assembly approach is reported to prepare poly(3-hexylthiophene) (P3HT)/cadmium selenide quantum dot (CdSe QD) hybrid coaxial nanowires, which show enhanced photoconductivity compared with the pristine P3HT nanowires and the blended nanocomposites.

    8. Microwave-Assisted One-Pot Synthesis of Hyperbranched Epoxide-Amine Adducts (pages 1424–1427)

      Julia Theis, Helmut Ritter and Joachim E. Klee

      Version of Record online: 10 JUL 2009 | DOI: 10.1002/marc.200900157

      Thumbnail image of graphical abstract

      The nitrile moiety of 1 was hydrogenated under microwave irradiation using 1-methyl-1-cyclohexene as an internal hydrogen source forming the AB2 monomer 2 as an intermediate. This monomer reacts immediately to give hyperbranched epoxide-amine adducts 3. The formation of a homologous series (n = 2, 3, 4, …) of oligomers was detected by mass spectrometric investigations and DLS experiments. In the presence of Cu2+ ions, large aggregates were formed.

      Back Cover: A macrocyclic monomer that provides a steric canopy over one face of the appended aryl ring is prepared and a poly(p-phenylene ethynylene) derivative prepared from it is tested for nitroorganic detection.
