A series of m ‐terphenyl‐substituted silanes was prepared and studied with regard to the steric and electronic interactions between the silyl core and the terphenyl shroud. Only weak conformational preferences were observed for the core, but the π‐basicity of the lateral rings led to distinct nuclear magnetic resonance shifts, and o ‐fluorine atoms led to through‐space coupling effects.
