Abstract

Abstract : A new sign has risen in the porphyrin sky ! Stable isoporphyrins can be produced as non‐aromatic NIR dyes in yields up to 36% by a one‐pot process. Non‐planar distortion modes are the key to control the optical spectra and the occurrence of isomers by means of synthesis. For the first time, the redox chemistry of isoporphyrins was studied by electrochemical methods, which is significant with regard to potential applications in photovoltaics. The cover image shows the linear display of a zinc isoporphyrin as a constellation in the night sky of the northern hemisphere, between the constellations Orion and Big Dipper. In the foreground, the UV spectrum with the prominent NIR absorptions around 900 nm piles up as a mountain relief. More information can be found in the Full Paper by M. Bröring et al.
