Front Cover: Phosphine Oxidation with Water and Ferrocenium(III) Cation Induced by Visible‐Light Irradiation (Chem. Eur. J. 70/2018)

Abstract

The ferrocenium(III) cation can be excited by visible light to give a photoexcited species, which is further quenched by an electron transfer from phosphine, with the formation of ferrocene and phosphine radical cation. Here, excitation and quenching of the fluorescence behavior of the ferrocenium(III) cation can be expressed as the beating of a tsuzumi and the propagation of its sound, respectively. The tsuzumi is a Japanese traditional hand drum that resembles the molecular shape of metallocenes. More information can be found in the Communication by Y. Nishibayashi, et al. on page 18618.
