    The acyclic diene metathesis (ADMET) polymerization of polar dienes by the action of the dicationic ruthenium alkylidene [Ru(DMF)3(1,3-dimesitylimidazolin-2-ylidene)(CH-2-(2-PrO-C6H4)2+ 2BF4] under biphasic conditions using 1-butyl-2,3-dimethylimidazolium tetrafluoroborate and 1,2,4-trichlorobenzene allows for the high yield synthesis of high-molecular-weight polymers (inline image ≤ 40 000 g mol−1, yields ≤ 99%). Ru-contamination of the polymers without any additional purification is as low as 1.2 ppm.

    Front Cover: A natural anionic polymer sodium alginate is applied to protect insulin from trypsin degradation in the human small intestine. Such an inhibitor can be used in all kinds of dosage forms. Its mechanism may be attributed to preventing tryptic active sites from accessing the macromolecular substrates. Further details can be found in the article by Y. Lv, J. B. Zhang, Y. Z. Song, B. Wang, S. J. Wang, S. Zhao, G. J. Lv,* and X. J. Ma* on page 1606.

    Back Cover: The fabrication and morphologies of three-dimensional polystyrene-block-polydimethylsiloxane (PS-b-PDMS) nanostructures confined in the nanopores of anodic aluminum oxide (AAO) templates are studied. The block copolymers wet the nanopores using a novel solvent-annealing-induced wetting method. In addition, the morphologies of the PS-b-PDMS nanostructures are controlled by changing the wetting conditions. These three-dimensional nanostructures can serve as nanotemplates for refilling with other functional materials. Further details can be found in the article by C.-J. Chu, P.-Y. Chung, M.-H. Chi, Y.-H. Kao, and J.-T. Chen* on page 1598.
