title: Polymorphism in new thienothiophene-thiazolothiazole organic semiconductors.
abstract: The front cover artwork is provided by J. A. Schneider from D. Perepichka's group (McGill University). The image shows two packing motifs of the same organic semiconductor, which either hinder or facilitate charge transport. In the foreground the crystal polymorphs and a single crystal field-effect transistor are pictured. Read the full text of the article at 10.1002/cphc.201500066.
