Front Cover: Diindeno-Fused Corannulene-Extended Tetrathiafulvalenes (ChemPhotoChem 10/2024)

Abstract

The Front Cover illustrates the sequential one-electron oxidations of corannulene-extended tetrathiafulvalene and the accompanying color changes. Clar sextets for each redox state are highlighted by filled circles within the structures. The dication seems to exhibit some diradicaloid character in line with the fact that four favorable Clar sextets can be drawn for the diradicaloid resonance structure and only two for the quinoid structure. More information can be found in the Research Article by Mogens Brøndsted Nielsen and co-workers (DOI 10.1002/cptc.202400122).
