Discover the articles included in the February 2015 issue of New Journal of Chemistry.

NJC OFC Feb 2015 - Dr AakeroyDr Christer Aakeröy (Kansas State University, USA) designed the outside cover this month. In their article, Dr Aakeroy and his colleagues describe how a simple electrostatic view of hydrogen bonds can lead to predictable and highly site-specific molecular recognition events.

The deceptively simple act of molecular recognition is achieved by balancing a range of non-covalent forces, and the synthesis of more complex architectures requires a systematic and targeted application of hierarchical self-assembly. By addressing specific questions about how small molecules prefer to bind to each other, it may be possible to devise reproducible and reliable links between molecular structure and practical methodologies for directed non-covalent synthesis.

Molecular electrostatic potential dependent selectivity of hydrogen bonding, Christer B. Aakeröy, Tharanga K. Wijethunga and John Desper, New J. Chem., 2015, 39, 822-828. DOI: 10.1039/C4NJ01324GNJC IFC Feb 2015 - Dr Gauthier

The inside cover is proposed by Dr Gilles Gauthier (Universidad Industrial de Santander, Colombia) and co-workers to illustrate their study on the influence of the Mn precursor on the formation of polytypes.

The authors studied in detail the phenomenon and also prepared a new polytype using a specific chemical route. The results show that even small changes in the mean oxidation state of the transition metals can guide a synthesis route in different ways and lead to different polytypes.

Their work contributes to the understanding of the solid state reactivity, giving new insights in the synthesis of new compounds,  destined for magnetic materials and other applications.

Influence of the synthesis route on the formation of 12R/10H-polytypes and their magnetic properties within the Ba(Ce,Mn)O3 family, Mario A. Macías, Olivier Mentré, Caroline Pirovano, Pascal Roussel, Silviu Colis and Gilles H. Gauthier, New J. Chem., 2015, 39, 829-835. DOI: 10.1039/C4NJ00798K
