Inside Cover: Surface-Grafted Semiconductor Layer Prepared by Surface Initiated Ring-Opening Polymerization of L-Lysine NCA Derivatives (Chem. Asian J. 8/2014).

Semiconductors Surface ‐ grafted π ‐ conjugated organic semiconductor layers are attractive for organic electronics and surface nanotechnologies. Zhibo Li and co ‐ workers from the Institute of Chemistry, Chinese Academy of Sciences (ICCAS) developed a simple and universal method to construct compact polymeric n ‐ type semiconductor films via surface ‐ initiated ring ‐ opening polymerization (SI ‐ ROP) of functional lysine N ‐ carboxylic anhydride (NCA) monomers. In their Communication on page 2036   ff., highlighted on the Inside Cover, the research group from ICCAS reports on the preparation of asymmetric and symmetric perylene bisimide (PBI) ‐ functionalized L ‐ lysine NCAs (PBI ‐ NCAs). Using silicon wafers functionalized with a primary amine as substrate, they successfully grated a layer of semiconductors by this method. Their study holds promise for large ‐ area surface modifications for electronic devices directly from organic semiconductor ‐ functionalized monomers. [ABSTRACT FROM AUTHOR]
