Unstoichiometric Suzuki–Miyaura cyclic polymerization of extensively conjugated monomers?
Polymer Chemistry Pub Date: 2019-01-31 DOI: 10.1039/C8PY01741G
Abstract
Suzuki–Miyaura polycondensation of an excess of linearly extended, conjugated dibromo monomer with meta-phenylenediboronate and of an excess of the extensively conjugated, kinked dibromo monomer with para-phenylenediboronate in the presence of tBu3PPd(0) precatalyst, which has a strong propensity for intramolecular π-face transfer, afforded cyclic polymers with Mn 12?400–6400, although unstoichiometric polycondensation generally affords linear polymers.
