Access to Functionalized Pyrenes, Peropyrenes, Terropyrenes, and Quarterropyrenes via Reductive Aromatization

Abb.: Wiley-VCH

Pyrene has extensively been studied as archetypical fluorophor by synthesis and photophysical research groups. Much less was known for its higher homologues, so called ropyrenes. We developed a modular synthesis strategy building up their molecular backbones and furnishing the target dyes including an unprecedented quarteropyrene via a reductive aromatization step. This series of ropyrene silylethers was systematically studied by XRD, UV-Vis- and fluorescence spectroscopy as well as cyclovoltammetry and (TD-)DFT calculations correlating physical properties and frontier orbitals with their size.
