Angewandte Chemie 37/2015: Fine Control
In this issue, M. Prato et al. review the covalent functionalization of graphene on substrates. How can chemical structures and bandgaps be fine-tuned for electronic applications? In a Minireview, T. Wang and J. Gong discuss single-crystal semiconductors for water splitting. The Highlight deals with N6-methyladenine in eukaryotic genomes (D. Summerer). In his Editorial, S. Kitagawa reflects on porous materials and the age of gas.
In the Communications section, X. Zou et al. demonstrate how coupling Mo2C with nitrogen-rich nanocarbon leads to efficient electrocatalytic sites for hydrogen evolution (see picture). F. Jäkle et al. report on a versatile and facile access to unconstrained conjugated organoborane macrocycles. K. J. M. Bishop et al. explain how amphiphilic nanoparticles control the growth and stability of lipid bilayers with open edges. S. Gianni et al. establish that frustration sculpts the early stages of protein folding.
Nanodiamonds Lined Up
Polymerization of carbon cage structures to linear diamond-like structures inside carbon nanotubes
The inner space of carbon nanotubes can act as a template for the synthesis of nanodiamond-like carbon chains. As a team of scientists from Japan, Germany, and the United States report in the journal Angewandte Chemie, this templated polymerization approach paves the way for the design of novel one-dimensional nanomaterials.
Nanosized materials such as nanowires offer unique properties that are completely distinct from those of the bulk materials. However, one-dimensional nanostructures are difficult to synthesize. In an international cooperation, Hisanori Shinohara from Nagoya University in Japan and his colleagues have developed a method that uses carbon nanotubes as a reaction vessel for the templated polymerization of linear-chain nanomaterials. The idea was that during polymerization, the small precursor molecules would naturally adopt the one-dimensional structure of the tubes only if their inner diameter is small enough. Larger diameters would offer too much space so that the polymerization could terminate or become uncontrolled. By using this method, Shinohara and his colleagues were able to synthesize a one-dimensional nanodiamond polymeric structure by a relatively simple annealing technique. They describe their approach: "The present template-based approach for the synthesis of linear-chain diamondoid polymers is entirely different from conventional chemical approaches."
