Doping-induced solubility control is a patterning technique for semiconducting polymers, which utilizes the reduction in polymer solubility upon p-type doping to provide direct, optical control of film topography and doping level. In situ direct-write patterning and imaging are demonstrated, revealing sub-diffraction-limited topographic features. Photoinduced force microscopy shows that doping level can be optically modulated with similar resolution.

For efficient charge separation and extraction in a device, the specific characteristics of processing additives, such as high boiling points and selective solubility, provide a special opportunity to form a well phase-separated nanomorphology in a bulk-heterojunction (BHJ) film. The applications of processing additives to commercial OPVs can be further developed with respect to future demands for various BHJ materials, such as high performance, long-term stability and eco-friendly fabrication.

Supramolecular peptide structures: The RFFFR peptide self-assembles into fibers that entangle into sphere-like structures. These spheres untangle below a critical concentration and so might be applicable as a drug-delivery system. Furthermore, the spheres conduct electricity, and the fibers might also find applications in molecular electronics.

Large ratio, small size: Presented is the first example of a new class of donor–σ–acceptor rectifiers: hemibiquinones (HBQs). HBQs possess donor and acceptor moieties that are electronically isolated by inter-ring torsion. A HBQ–dinitrile self-assembles on a template-stripped gold surface through directed chemisorption forming a 1.1 nm-thick monolayer. Rectification is measured through the monolayer or single molecules by using three different top electrode arrangements.
