The bloom of a sunflower is used to describe the highly symmetric planar structure of octathio[8]circulene, whose trivial name “sulflower” derives from sulfur and flower (see cover picture). In their Communication on page 7367 ff., V. G. Nenajdenko and co-workers describe the synthesis and characterization of sulflower, a molecule that can be considered as a new form of carbon sulfide and as an oligothiophene, that is, as both inorganic and organic.

Droplet-based microfluidics enables high-throughput applications, such as the optimization of reaction conditions or the analysis of complex biological processes. Current developments in this field are discussed by R. F. Ismagilov and co-workers in their Review on page 7336 ff.

Metal–Organic Frameworksfor002

In their Communication on page 7358 ff., N. R. Champness, P. Hubberstey, M. Schröder, and co-workers compare the H2 sorption of a series of metal–organic frameworks. Those with smaller pores adsorb higher densities of H2, whereas those with larger pores have higher maximum H2 storage capacities.

DNA Structuresfor003

A. J. Turberfield and co-workers have incarcerated cytochrome c: single molecules of the protein are trapped in rigid tetrahedral DNA cages, which can also accommodate larger globular proteins. These results are discussed in the Communication on page 7414 ff.
