▶ Nanostructure control in polymer solar cells by self-organization (pages 8–17) Keisuke Tajima and Kazuhito Hashimoto
▶ Polymer solar cells (PSCs) based on “bulk heterojunctions” use a simple mixture of electron donor and acceptor materials in thin films. A bottom-up approach, such as the self-organized formation of inorganic and organic nanostructures, is described, which allows the construction of reproducible nanostructures that are suitable for both efficient charge separation and transport inside such films. Abstract
▶ Enantioselective epoxidation of electron-deficient olefins: an organocatalytic approach (pages 18–39) Katharina M. Weiß and Svetlana B. Tsogoeva
▶ An overview on asymmetric epoxidation reactions with electron-deficient olefins for the preparation of epoxyketones and epoxyaldehydes is presented. These compounds are valuable building blocks for the synthesis of enantiomerically pure complex molecules, in particular, biologically active compounds and pharmaceuticals. The scope and limitations are discussed, and the considerable advances in this field have been reported using chiral organocatalysts, such as chiral amines, phase-transfer catalysts (PTCs), chiral guanidines, and chiral peroxides.

Records and Challenges
▶ The longest quinoidal oligothiophene: A Raman story (pages 45–53) Juanjuan Casado and Juan T. López Navarrete
▶ Quinoidal oligothiophenes are promising materials as ambipolar transporters in organic electronics. Surprisingly, they are also magnetic active substrates in their uncharged state. The series of Raman findings that allowed us to justify these magnetic properties in the longest quinoidal oligothiophene, as a result of its biradicaloid character and the participation of low-lying-energy triplet states, is described.

▶ Fabrication of the smallest organic nanocolloids by a top-down method based on laser ablation (pages 54–58) Teruki Sugiyama and Tsuyoshi Asahi
▶ Stable aqueous colloids of organic nanoparticles were tailored by laser ablation of microcrystalline quinacridone in water. The nanocolloids were flaky in shape and had dimensions of 13 (5) nm by 1.4 (0.5) nm. Abstract
