Monodentate DNA binding of [PtCl(dien)]+ (dien=diethylenetriamine) complexes may considerably affect the biophysical properties of DNA and consequently downstream cellular processes as a result of a large increase in the bulkiness of the nonleaving ligand by multiple methylation (see illustration).

Selective DNA detection: The fluorescence, from stable cationic QDs, is quenched by 90% on complexation with modified DNA molecules. The QD–DNA probe is capable of detecting pathogenic DNA fragments at concentrations as low as 200 nM in solution and shows selective fluorescence recovery in the presence of target DNA (see spectrum c in figure) vs noncomplementary DNA (spectrum d).

Organolithium chemistry! An overview of the structure formation principles and the strong structure–reactivity relationship of lithium organics is given. By means of the commonly used lithium bases the deaggregation of the oligomeric parent structures to small adducts is presented (see examples) and compared to the related chemistry of lithiosilanes.

The right path : The mechanism of organocatalyzed Michael addition between propanal and methyl vinyl ketone is investigated using the density functional and ab intio methods. The kinetic preference for the formation of key intermediates is established in an effort to identify the competing pathways associated with the reaction. The effect of co‐catalyst/protic solvent on the energetics of the reaction is also studied

Self‐assembly line : In the presence of a DNA analyte or low‐molecular‐weight substrates, multicomponent nucleic acids self‐assemble into cooperatively stabilized functional nanostructures (see scheme) that activate DNAzyme cascades.

Fast moving : A new pentad (see figure) composed of silicon phthalocyanine (SiPc), as electron donor, that is connected with two units of naphthalenediimide (NDI) and fullerene C60, as electron acceptors, undergoes fast and efficient charge‐separation processes via the NDI and SiPc singlet excited states.

Change happens : Acridine–carbon nanotube nanohybrids were built (see figure) and their photoinduced electron‐transfer properties investigated, showing variable behaviour depending on the acridine partner.

Supra‐mega ion pairing : Multicationic organoruthenium dendrimers show a notable tendency to self‐aggregate when the concentration is increased, leading to megamers. This tendency increases with the generation. The self‐aggregation of dendrimers to megamers is coupled with a decrease in the extent of ion pairing, as illustrated.

Making connections : A hydroxy‐centered trinuclear nickel cluster has been employed to construct a highly connected, highly symmetric framework with a uninodal nine‐connected topology. An array of triakis tetrahedra leads to a biporous intersecting‐channel system (see picture).
