19_05b/2007Inside Front Cover: Photoinduced Nitrosyl Linkage Isomers Uncover a Variety of Unconventional Photorefractive Media (Adv. Mater. 5/2007)

Photorefraction, i.e., a light-induced change of the refractive index, is uncovered as general feature of light-induced linkage isomers in [ML5NO]n± compounds, independent of the metals M, the ligands L, or the charge n. Dominik Schaniel and co-workers report on p. 723 that huge amplitudes of refractive-index changes, up to 10–2, give rise to pronounced holographic light scattering, which is visualized by impressively bright cones of scattered light, as shown on the inside cover.
