A novel strategy to enhance the cyclability of organic sodium-ion batteries is developed by applying a selectively permeable membrane to allow the pass of Na ions but block the slight dissolved active molecules and thereby inhibits the further dissolution. After utilization of the membrane, the batteries show highly enhanced cyclability. Such strategy can be potentially extended to many organic materials with low solubilities.

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.

A patterning technique for conductive polymers is demonstrated, based on UV light exposure through a photo mask followed by vapor phase polymerization. High-resolution patterns and optical gradients in poly(3,4-ethylenedioxythiophene):tosylate can be fabricated, where the conductivity is controlled over more than six orders of magnitude.

Acene from a condensation: Four different bent benzo[a]naphtho[2,3-i]phenazines are efficiently synthesized by condensation of aromatic diamines with 1,2-naphthalenedione. The resultant azaacenes are spectroscopically and crystallographically characterized. Optical properties are studied and compared with those of the isomeric linear azaacenes.
