Shilun Qiu, Guangshan Zhu and co-workers have made a microporous organic-inorganic silsesquioxane-based framework, JUC-Z1, which is an effective absorber of both benzene and water. The team used a Yamamoto-type of Ullmann cross-coupling reaction to make the framework. ‘Its ability to selectively adsorb benzene makes JUC-Z1 greatly promising for applications dealing with environmental aromatic pollutant problems,’ say Qiu and Zhu.

Hiromi Tobita and colleagues look into the reactions of bis(silyl)hydrido molybdenum and tungsten complexes in this Dalton Transactions Hot article. They were able to generate a 16-electron species, which when reacted with nitriles led to hydrosilylation of their CN triple bonds to give N-silylimine complexes, even at room temperature.

Controlling the growth of low dimensional nanostructures of organometallic complexes with well-defined properties is a significant and ongoing challenge within nanoscience and nanotechnology.

Huibiao Liu, Yuliang Li and co-workers, from the CAS Key Laboratory of Organic Solids in Beijing have made inroads into this challenge by controlling the growth of the nanowire–nanotube junctions of a dichloro-bridged dimeric iridium complex optimising the material for use in LEDs.
