      Front Cover: Making use of photodegradation: photooxidative chain-scission of a precursor to poly(3,4-diphenyl-2,5-thienylene vinylene) increases the solubility of the UV exposed areas, allowing for selective dissolution (a positive tone resist). The resulting pattern (the unexposed regions) retain pristine optical and electrical properties. The process results in single micron resolution of an insoluble active material. Further details can be found in the article by R. S. Johnson,* J. J. Haworth, P. S. Finnegan, D. R. Wheeler, and S. M. Dirk* on page 1116.

      Back Cover: Linear dendritic block co-polymers combine linear and dendritic polymers in the same macromolecule. Synergies between both types of structures can be exploited to achieve hybrid polymers with excellent control of functionality, good processability, and self-assembling properties, both in solution and in bulk. Synthetic approaches are reviewed here, as well as their most important application as stimuli-responsive materials. Further details can be found in the article by E. Blasco, M. Piñol,* and L. Oriol* on page 1090.

    1. Conjugated Polymer Patterning through Photooxidative Backbone Cleavage (pages 1116–1120)

      Ross S. Johnson, Jacob J. Haworth, Patrick S. Finnegan, David R. Wheeler and Shawn M. Dirk

      Version of Record online: 17 APR 2014 | DOI: 10.1002/marc.201400133

      Thumbnail image of graphical abstract

      A xanthate precursor to poly(3,4-diphenyl-2,5-thienylene vinylene) is shown to photopattern as a positive tone resist. Photooxidative cleavage of the polymer backbone increases the solubility of the light-exposed areas, allowing for pattern formation. Single micrometer resolution of an insoluble active material is achieved without compromise to the polymer's properties.

    2. Ambient Temperature Ligation of Diene Functional Polymer and Peptide Strands onto Cellulose via Photochemical and Thermal Protocols (pages 1121–1127)

      Thomas Tischer, Tanja K. Claus, Kim K. Oehlenschlaeger, Vanessa Trouillet, Michael Bruns, Alexander Welle, Katharina Linkert, Anja S. Goldmann, Hans G. Börner and Christopher Barner-Kowollik

      Version of Record online: 6 APR 2014 | DOI: 10.1002/marc.201400088

      Two ambient temperature strategies—one photochemically, one thermally driven—for the modification of solid cellulose substrates based on the hetero Diels–Alder ligation with macromolecular and peptide diene compounds are reported.

    3. Control of Glycopolymer Nanoparticle Morphology by a One-Pot, Double Modification Procedure Using Thiolactones (pages 1128–1134)

      An efficient one-pot, two-step procedure employing thiolactone containing polymers leads to glycopolymer nanoparticles with control over morphology by adjusting the size of the alkyl chain of the reactants.

      Chain-End-Functionalized Polyphosphazenes via a One-Pot Phosphine-Mediated Living Polymerization (pages 1135–1141)

      Sandra Wilfert, Helena Henke, Wolfgang Schoefberger, Oliver Brüggemann and Ian Teasdale

      Version of Record online: 4 APR 2014 | DOI: 10.1002/marc.201400114

      Well-defined, mono-end-functionalized polyphosphazenes are prepared via living cationic polymerization. Dichlorophosphoranes with (protected) functional groups are prepared in situ from commercially available triphenylphosphines and employed as initiators for the polymerization of trichlorophosphoranimine. NMR spectroscopy and SEC analysis show that the molecular weights can be controlled via the monomer:initiator ratio to give α-chain-functionalized poly(organo)phosphazenes for the preparation of macromolecular constructs.

    5. Planar Conjugated Polymers Containing 9,10-Disubstituted Phenanthrene Units for Efficient Polymer Solar Cells (pages 1142–1147)

      Novel planar D–A alternating conjugated polymers (P1-4) with 9,10-disubstituted phenanthrene as the donor unit and 5,6-bis(octyloxy)benzothiadiazole as the acceptor unit are synthesized and used as donor materials for BHJ PSCs. The best PCE of 4.24% is achieved for the blends of P1-4 and PC71BM.

    6. pH-Induced Inversion of Water-in-Oil Emulsions to Oil-in-Water High Internal Phase Emulsions (HIPEs) Using Core Cross-Linked Star (CCS) Polymer as Interfacial Stabilizer (pages 1148–1152)

      Using pH-responsive core cross-linked star (CCS) polymer as the emulsifier, inversion of emulsion type from common water-in-oil emulsions to oil-in-water gelled high internal phase emulsions (HIPEs) is achieved by simply adjusting the pH.
