The Physical Properties and Self-Assembly Potential of the RFFFR Peptide

The Physical Properties and Self‐Assembly Potential of the RFFFR Peptide

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.

Head-to-Head Linkage Containing Bithiophene-Based Polymeric Semiconductors for Highly Efficient Polymer Solar Cells

Head‐to‐Head Linkage Containing Bithiophene‐Based Polymeric Semiconductors for Highly Efficient Polymer Solar Cells

Narrow bandgap (1.37–1.46 eV) polymers incorporating a head-to-head linkage containing 3-alkoxy-3′-alkyl-2,2′-bithiophene are synthesized. The head-to-head linkage enables polymers with sufficient solubility and the noncovalent sulfur–oxygen interaction affords polymers with high degree of backbone planarity and film ordering. When integrated into polymer solar cells, the polymers show a promising power conversion efficiency approaching 10%.

Surprisingly Big Rectification Ratios for a Very Small Unimolecular Rectifier

Surprisingly Big Rectification Ratios for a Very Small Unimolecular Rectifier

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.

Synthesis of Alkynylated Benzo[a]naphtho[2,3-i]phenazine Derivatives

Synthesis of Alkynylated Benzo[a]naphtho[2,3-i]phenazine Derivatives

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.
