51_37/2012Cover Picture: Solution-Phase and Magnetic Approach towards Understanding Iron Gall Ink-like Nanoassemblies (Angew. Chem. Int. Ed. 37/2012)

Compounds related to iron gall inks namely iron complexes of pyrogallol[4]arenes, have been structurally elucidated by J. L. Atwood and co-workers by using a combination of solid-state magnetic and in situ neutron scattering methods, as reported in the Communication on page 9263 ff. The cover picture highlights the degradation of an ancient manuscript inscribed with iron gall inks composed of iron complexes of polyphenolic tannic acids, possibly gallic acid or pyrogallols.
