Discover the last issue of New Journal of Chemistry for the year 2014.

NJC Dec 2014 OFC Dr SoferThis month, our outside cover illustrates an article written by Dr Zdeněk Sofer (Institute of Chemical Technology, Czech Republic) and his colleagues, focusing on graphite oxides.

In their paper, the authors show that more complex products (large amounts of complex ions) than water vapor and carbon mono- and dioxide are produced during the exfoliation process. The team came to the conclusion that the full understanding of the exfoliation mechanism and products is crucial for reproducible scalable synthesis of reduced graphenes on a large scale.

NJC Dec 2014 IFC Prof. Uchida

Prof. Kingo Uchida (Ryukoku University, Japan) and his co-workers have designed the inside cover. They focused their research on the development of molecular switches, in particular photoactive systems that are a major challenge in the context of molecular devices and light-responsive systems.

In their paper, they present the synthesis of a diarylethene with an attached malachite green moiety and study the photochromism and halochromism of six states (neutral, mono- and dicationic states under both open- and closed-ring isomeric states) to clarify the effect of combining two dyes. The data obtained will contribute to the design of pH sensitive photoswitches, especially for biological applications and their successful incorporation in various applications and in switchable molecular-based devices.

Also discover a Focus, written by Dr Borkovec (University of Geneva, Switzerland) and his colleagues, dedicated to the intrinsic approach describing microscopic ionization equilibria. The authors present an intrinsic description with examples of increasing complexity, thereby highlighting various strategies to extract the relevant parameters. They also address the notion of group transferability, then the central idea of cluster expansion of the free energy, and finally molecular symmetries and homologous series.
