Abstract
Monomer 3 was easily accessed from 1 by methylation with methyl triflate followed by bromination with NBS. The authors used a Suzuki-Miyaura-type coupling to react 3 with 4 to form a conjugated diblock polymer. Polymer 5 shows a red-shifted absorption and emission compared to monomer 3, as expected, and a small Stokes shift, which suggests that the polymer has a relatively rigid backbone. Polymer 5 was emissive in solution and maintained some fluorescence in the solid state.Keywords
