Accessing new microporous polyspirobifluorenes via a C/Si switch?
Chemical Communications Pub Date: 2020-07-24 DOI: 10.1039/D0CC02767G
Abstract
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.
