Microporous spirosilabifluorene networks were synthesized via Yamamoto coupling of tetrabromospirosilabifluorene precursors. They exhibit bright fluorescence that is quenched in the presence of nitroaromatics. The C/Si switch has subtle effects on the optical properties of the spirobifluorene network and provides a convenient route to 3,3',6,6'-coupled and other polybifluorenes.
