  1. Imparting Nonfouling Properties to Chemically Distinct Surfaces with a Single Adsorbing Polymer: A Multimodal Binding Approach

    Ângela Serrano, Stefan Zürcher, Samuele Tosatti and Nicholas D. Spencer

    Article first published online: 9 FEB 2016 | DOI: 10.1002/marc.201500683

    Nonfouling, surface-active polymers carrying binding groups capable of adsorbing onto different substrates are described. The developed versatile postmodification protocol allows the creation of a polymer that maintains its surface functionality under a variety of harsh conditions. Ethylene glycol surface-density calculations show that this strategy generates a significantly denser packing than current approaches and readily allows the fabrication of a broad combinatorial matrix.

  2. Color-Transformable Silicone Elastomers Prepared by Thiol-Ene Reaction with Potential Application in UV-LEDs

    Yujing Zuo, Zhiming Gou, Jie Zhang and Shengyu Feng

    Article first published online: 4 FEB 2016 | DOI: 10.1002/marc.201500671

    The first example of a dual-component elastomer that can emit yellow and red primary colors at different irradiation conditions. Colorful UV-LEDs were further fabricated from the solution medium through an “in situ” cross-linking method, and the device also showed color changing property when the light was turned on.

  3. Orthogonal Synthesis of Block Copolymer via Photoinduced CuAAC and Ketene Chemistries

    Mehmet Atilla Tasdelen, Omer Suat Taskin and Cumali Celik

    Article first published online: 4 FEB 2016 | DOI: 10.1002/marc.201500563

    A simple approach combining photoinduced copper (I)-catalyzed alkyne-azide cycloaddition (CuAAC) and ketene chemistry reactions is proposed to synthesize poly(ethylene glycol)-b-polystyrene copolymer starting from easily accessible blocks, poly(ethylene glycol) methyl ether, and azido terminated polystyrene. The process proceeds either simultaneously or sequentially in a one-pot procedure under near-visible light irradiation.

  4. Preparation of Bottlebrush Polymers via a One-Pot Ring-Opening Polymerization (ROP) and Ring-Opening Metathesis Polymerization (ROMP) Grafting-Through Strategy

    Scott C. Radzinski, Jeffrey C. Foster and John B. Matson

    Article first published online: 4 FEB 2016 | DOI: 10.1002/marc.201500672

    Thumbnail image of graphical abstract

    Bottlebrush polymers are synthesized using a ring-opening polymerization (ROP) and ring-opening metathesis polymerization (ROMP) strategy. ROP and ROMP are conducted sequentially in the same pot yielding well-defined bottlebrush polymers with molecular weights in excess of 106 Da. Spectroscopic analyses confirm excellent control over both polymerization steps. Bottlebrush polymers are imaged using atomic force microscopy and stain-free transmission electron microscopy.

  5. Diblock Polyelectrolytic Copolymers Containing Cationic Iron and Cobalt Sandwich Complexes: Living ROMP Synthesis and Redox Properties

    Haibin Gu, Roberto Ciganda, Ricardo Hernandez, Patricia Castel, Pengxiang Zhao, Jaime Ruiz and Didier Astruc

    Article first published online: 3 FEB 2016 | DOI: 10.1002/marc.201500679

    Diblock polyelectrolytes containing both iron and cobalt electron-reservoir sandwich complexes in their cationic forms are synthesized by living ring-opening metathesis polymerization (ROMP) with Grubbs' third generation catalyst and possess a rich redox chemistry. The full chemical and electrochemical reversibilities of the distinct cathodic cyclovoltammetry waves allow to determine the number of monomer units of each metalloblock.
