Understanding the Microstructure of Poly(p-phenylenevinylene)s Prepared by Ring Opening Metathesis Polymerization Using 13C-Labeled Paracyclophanediene Monomers
Abstract
Selectively main chain <sup>13</sup>C-labeled poly(p-phenylenevinylene)s (PPVs) were synthesized by ring-opening metathesis polymerization (ROMP) of <sup>13</sup>C-labeled dialkoxy-substituted [2,2] paracyclophane-1,9-dienes (<b>M</b>) using the Grubbs second generation ruthenium carbene complex (<b>G2</b>). Analysis of the natural abundance and <sup>13</sup>C-labeled PPVs by NMR spectroscopy showed no main chain structural defects for these polymers. Comparison of the in situ <sup>1</sup>H and <sup>13</sup>C NMR spectroscopy during the ROMP of labeled and unlabeled monomer enabled the active ruthenium carbene chain ends present during the initiation and propagation reaction to be definitively characterized. Using <sup>13</sup>C NMR spectroscopy, the regiochemistry of the propagation of the asymmetric monomer <b>M</b> with <b>G2</b> was found to be essentially regiorandom.
