Improved Suzuki polycondensation: A diiodo versus a dibromo monomer

This paper compares a dibromo and a structurally strictly related diiodo monomer in regard to the respective achievable molecular weights and the degree of incorporated phosphorus when subjected to the Suzuki polycondensation. The diiodo monomer gives – by a factor of roughly two – a higher molecular weight PPP (Pn up to 143) and virtually negligible phosphorus incorporation.
