50_31i/2011Inside Cover: Synthesis and Structural Characterization of Crystalline Nonacenes (Angew. Chem. Int. Ed. 31/2011)

Nonacene crystals possess a bright metallic sheen and their solution absorption spectra fit well in the series of silylethyne-substituted acenes. As J. E. Anthony et al. report in their Communication on page 7013 ff., crystallographic analysis of functionalized nonacenes confirmed the nine-ringed structure and showed that π-stacked arrangements exist in the solid state. EPR analysis showed that the nonacenes possess radical character, and exposure of nonacene solutions to light caused decomposition to form a red-fluorescent compound.
