Facile synthesis of fluorene-based π-conjugated polymers via sequential bromination/direct arylation polycondensation

摘要

The synthesis of fluorene-based π-conjugated polymers via sequential bromination and Pd-catalyzed direct arylation polycondensation was demonstrated; the protocol allows dual functionalization of each aromatic monomer in one-pot fashion. This synthetic protocol afforded the corresponding polymers with high molecular weights in good yields (up to yield 80%, Mn 34,500).
