53_11/2014Cover Picture: Tuning Ground States of Bis(triarylamine) Dications: From a Closed-Shell Singlet to a Diradicaloid with an Excited Triplet State (Angew. Chem. Int. Ed. 11/2014)

Tuning the ground states ... ... of bis(triphenylamine)benzedine bipolarons through substituent effects is described by X. Wang et al. in their Communication on page 2857 ff. The ground-state structures of three bis(triphenylamine) dications, isolated by using weakly coordinating anions, were tunable through the donor substituents at the para positions of the triphenylamines. This gave rise to closed-shell singlets and a new and stable diradicaloid structure motif with an excited triplet state in the solid state.

Chemical Imaging of Materialsfor001

As shown by A. Centrone et al. in their Communication on page 2852 ff., by measuring the thermal expansion of metal–organic frameworks following absorption of IR light, an AFM tip maps the local chemical composition of such materials.


Directing self-assemblyfor002

Different cyanide-bridged clusters can be prepared form the same reaction mixture. H. Oshio and co-workers show in their Communication on page 2941 ff. the products are determined by a solution-state electron-transfer-coupled spin transition (ETCST) event.


Imagingfor003

An SmIII-functionalized dendrimer proved to be non-cytotoxic. S. V. Eliseeva, S. Petoud et al. show in their Communication on page 2927 ff. it functions as a bioprobe in both the visible or near-IR ranges in a live cell imaging experiment.
