A brighter future for siloles. Luminescent silole chromophores with the highest quantum efficiencies reported for a fully substituted monomeric silole are generated by altering the steric properties of the substituent groups. Treatment of 1,1‐dimethylsiloles with Bu 4 NF (TBAF) in THF rapidly gives stereospecific desilylation at room temperature (see scheme). Intense solid‐state photoluminescence is observed in thin films of the silole fluorophores.
