Polydispersity index conjugated polymers

Conjugated polymers (143) have also been prepared via coordination of iron(II) to dUithio >i5(3-hexyl-4-methylcyclopentadienide)arylenes (142) (Scheme 38)." " The weight average MW of these polymers were between 42,000 and 52,600 with polydispersity index (PDI) values ranging fiom 10.5 to 14.6. Oxidation of these polymers resulted in electrical conductivities ranging from 10 to 10 S/cm.
