  1. pH- and Sugar-Induced Shape Memory Hydrogel Based on Reversible Phenylboronic Acid–Diol Ester Bonds

    Hao Meng, Jing Zheng, Xiufang Wen, Zhiqi Cai, Jiawei Zhang and Tao Chen

    Article first published online: 29 JAN 2015 | DOI: 10.1002/marc.201400648

    A pH- and sugar-induced shape memory hydrogel is fabricated on the basis of dynamic phenylboronic acid (PBA)–diol interactions. The temporary shape of the hydrogel is fixed by PBA–diol ester bonds, and acidic conditions and aqueous solutions of monosaccharides including glucose and fructose are explored to induce the shape recovery process.

  2. Parallel Synthesis of Photoluminescent π-Conjugated Polymers by Polymer Reactions of an Organotitanium Polymer with a Titanacyclopentadiene Unit

    Yoshimasa Matsumura, Katsura Fukuda, Shinsuke Inagi and Ikuyoshi Tomita

    Article first published online: 29 JAN 2015 | DOI: 10.1002/marc.201400667

    Three kinds of fluorene-containing π-conjugated polymers that exhibit blue, green, and yellow emissions are prepared by a unique synthetic procedure implying the reactions of a regioregular organometallic polymer possessing titanacyclopentadiene units with electrophilic reagents such as sulfur monochloride, hydrochloric acid, and dichlorophenylphosphine, respectively.

  3. Synthesis of Triplet–Triplet Annihilation Upconversion Nanocapsules Under Protective Conditions

    Kartheek Katta, Dmitry Busko, Yuri Avlasevich, Rafael Muñoz-Espí, Stanislav Baluschev and Katharina Landfester

    Article first published online: 28 JAN 2015 | DOI: 10.1002/marc.201400670

    Triplet–triplet annihilation upconversion (UC) nanocapsules synthesized under protective conditions (i.e., complete darkness and argon atmosphere) demonstrate substantially increased UC efficiency and resolve partially the experimental challenges, arising if sustainable and reproducible UC results in confined environment are targeted.

  4. Coordination RC6H4S(CH2)8SC6H4R/(CuI)n Polymers (R (n) = H (4); Me (8)): An Innocent Methyl Group that Makes the Difference

    Pierre D. Harvey, Antoine Bonnot, Antony Lapprand, Carsten Strohmann and Michael Knorr

    Article first published online: 27 JAN 2015 | DOI: 10.1002/marc.201400659

    CuI reacts with RC6H4S(CH2)8SC6H4R to form the luminescent 1D coordination polymer [Cu4I42-PhS(CH2)8SPh}2]n and an unprecedented 2D network [Cu8I82-p-TolS(CH2)8STol-p}3(MeCN)2]n. X-ray data, respectively, reveal the presence of a closed cubane Cu4I4 and a fused cubane Cu8I8 motif. Spectroscopic evidence along with density functional theory (DFT) and TDDFT calculations show that the nature of the emissive states are cluster-centered (3CC*) mixed with 3M/XLCT* for both cases.

  5. Fabrication of Multicomponent Polymer Nanostructures Containing PMMA Shells and Encapsulated PS Nanospheres in the Nanopores of Anodic Aluminum Oxide Templates

    Hao-Wen Ko, Mu-Huan Chi, Chun-Wei Chang, Chun-Hsien Su, Tzu-Hui Wei, Chia-Chan Tsai, Chi-How Peng and Jiun-Tai Chen

    Article first published online: 26 JAN 2015 | DOI: 10.1002/marc.201400662

    The fabrication of poly(methyl methacrylate)/polystyrene nanostructures that contain poly(methyl methacrylate) shells and encapsulated polystyrene nanospheres is studied. The nanostructures are prepared using a solution-based template wetting method with anodic aluminum oxide templates. The compositions and morphologies of the nanostructures are controlled by the interactions between the polymers, solvents, and anodic aluminum oxide walls.
