      Front Cover: How to suppress the instability of liquid thin films on solid surfaces? Crystalline polymers (low weight percentage) dissolved in the liquid may produce in situ a network of the crystalline fibrils during the coating process. The network forms a liquid gel and prevents dewetting of the liquid. This strategy can be used to generate micropatterns of divserse materials such as polymers, metal oxides, and metals. This process allows fabrication of residual layer-free micropatterns, which has long been a challenge in soft lithography. Further details can be found in the article by J. Park , M. Park , and U. Jeong* on page 560.

    1. Sandwich Complex-Containing Macromolecules: Property Tunability Through Versatile Synthesis (pages 513–559)

      Alaa S. Abd-El-Aziz, Christian Agatemor and Nola Etkin

      Sandwich complexes-containing polymers are attractive complements of organic-based polymers as the former feature intriguing properties. These include excellent thermal stability, redox activity, magnetic, electrical, and optical properties. This review surveys many of the synthetic approaches that have resulted in tuning the properties of sandwich complex-containing macromolecules.

    1. Suppressing Instability of Liquid Thin Films by a Fibril Network and its Application to Micropatterning without a Residual Layer (pages 560–565)

      Jaeyoon Park, Minwoo Park and Unyong Jeong

      Article first published online: 4 FEB 2014 | DOI: 10.1002/marc.201300787

      A method for coating hydrophilic solutions on solid substrates is demonstrated. A network of polymer crystalline fibrils generated in situ during spin-coating suppresses effectively dewetting of the diluted polymer solution. This process allows residual layer-free micropatterning without using any etching process. This advantage is taken to generate micropatterns of polymer hydrogels and metal oxides (ZnO, In2O3).

    2. Facile Synthesis of β-Diketone Alcohols for Combined Functionality: Initiation, Catalysis, and Luminescence (pages 566–573)

      Xuepeng Zhang, Minxin Cui, Rui Zhou, Changle Chen and Guoqing Zhang

      Article first published online: 19 DEC 2013 | DOI: 10.1002/marc.201300834

      β-Diketones for combined functionalities are facilely synthesized through Claisen condensations between monoketones and ε-caprolactone. After chelation with appropriate Lewis acids such as Eu (III) or Tb (III), the complexes can serve as both initiator and catalyst for the ring-opening polymerization of lactide, and yield single-component luminescent polymers. This method has potential applications in producing β-diketone-based functional materials on large scale.

    3. Taurine-Induced Fabrication of Nano-Architectured Conducting Polypyrrole on Biomedical Titanium (pages 574–578)

      Taurine (2-aminoethane sulfuric acid), a bone metabolism-associated small biomolecule, is utilized to induce the fabrication of nano-architectured conducting polypyrrole on biomedical titanium. The ability of taurine being electropolymerized to polytaurine, as well as the order of restricted space constructed by polytaurine chains, determines the inducing growth orientation of nano-architectured conducting polypyrrole.

    4. Stimuli-Responsive Nanocomposite: Potential Injectable Embolization Agent (pages 579–584)

      Liver cancer remains a significant medical problem and one promising therapeutic approach is to embolize the tumor to deprive it of blood nutrients. Thermoresponsive nanocomposites are generated by grafting poly(N-isopropylacrylamide) side chains on bacterial cellulose nanowhiskers. The results suggest that these thermoresponsive nanocomposites offer appropriate physical and biological properties for embolization of hepatocellular carcinoma.

    5. Aziridine Termination of Living Anionic Polymerization (pages 585–589)

      Article first published online: 3 FEB 2014 | DOI: 10.1002/marc.201300860

      Aziridine-termination of living polymers was performed to quantitatively introduce amine functionalities at the polymer chain end in analogy to the well-established epoxide termination. The robust and easy protocol presents the first switch from carbanionic polymerization to living aza-anions by the addition of activated, i.e. tosylated aziridines which can be conveniently hydrolyzed to release the amines.
