Synthesis and Optoelectronic Properties of a Quinoxalino‐Phenanthrophenazine (QPP) Extended Tribenzotriquinacene (TBTQ).

A six‐step synthesis towards a tribenzotriquinacene (TBTQ) bearing three quinoxalinophenanthrophenazine (QPP) units is presented. The optoelectronic properties are investigated and the effect of the three‐dimensional arrangement of the individual QPP planes is examined using optical spectroscopy, electrochemical analysis and quantum‐chemical calculations.
