Poly[N-9'-heptadecanyl-2,7-carbazole-alt-5,5-(4',7'-di-2-thienyl-2',1',3'-benzothiadiazole)]. Commonly known as PCDTBT.

Mw 100,000-1000,000 by   GPC

For the deposition techniques, uniform, aggregate free coatings are essential and so lower molecular weights are often desirable. But meanwhile, the highest reported efficiencies for PCDTBT have generally been from higher molecular weight fractions.

By stocking a range of materials ViZuchem is now able to cater for a much wider range of research activities.
