Nine in a line: A multifaceted approach, including a silylethylene functionalization strategy, to the synthesis of stable nonacene derivatives (see picture, F green, Si blue) allows an unprecedented level of characterization, including electrochemical, photophysical, and crystallographic studies. The nonacenes show a strong S0–S1 transition and no fluorescence in the visible region.
