In this NJC paper, Liang Li (School of Materials Science and Engineering, East China University of Science and Technology, Shanghai, China) and Jianlin Shi (Shanghai Institute of Ceramics, Chinese Academy of Sciences, Shanghai, China) et al. report a simple but efficient, controlled thermal decomposition approach to fabricate polycrystalline mesoporous C-N-codoped anatase TiO₂.

The prepared material possesses a high surface area and extraordinary high photocatalytic degradation properties under visible irradiation.

In this NJC article, Cyrille Monnereau and his colleagues (University of Lyon, France) report an Atom Transfer Radical Polymerisation (ATRP) approach towards star-shaped chromophores, which bear hydrophilic oligomeric arms that form an “insulating shell” around the nano-sized molecules, resulting in their solubility in water with good conservation of their fluorescence quantum yield. These new amphiphilic chromophores are promising candidates for cellular fluorescence and photodynamic therapy. The authors claim that this synthetic strategy for photoactive species is straightforward and adaptable.

In this NJC paper, Marina Lezhnina et al (Muenster University of Applied Sciences-Chemical Engineering, Germany) report the synthesis and photophysical properties of Eu complexes attached to epoxy-functionalized phenantroline ligands.

The authors show how these complexes can be conveniently attached to thiol groups, in the present example gluthathione, and still retain the characteristic red emission of Eu centers.

In this NJC Hot paper, Fucke et al. attempt to answer a very important question relating to co-crystal formation and screening. Piroxicam, a non-steroidal anti-inflammatory drug, was chosen as a model system and subjected to extensive co-crystal screening using twenty different acids as co-crystal formers, six crystallisation techniques and five solvents. The work explores in comprehensive detail the use of different techniques for obtaining co-crystals and compares their efficacy. The authors offer several thoughts on how their results might usefully be applied to improve co-crystal screens.

In this NJC paper, Anna  Dolega and co-workers (Gdansk University of Technology, Poland) have prepared three imidazolium silanethiolates relevant to the active site of cysteine protease.

By using solid state characterization techniques and modeling, the authors were able to present the first example of proton transfer along the chain of NH^+…S^– hydrogen bonds.  A cooperative effect in the chain consisting of silanethiolate and imidazole residues linked by NH^+…S^– hydrogen bond was proposed to be due to the polarization of electron density connected with the increase in the Mulliken partial charge on the sulfur atom.
