Poly[N-9′-heptadecanyl-2,7-carbazole-alt-5,5-(4′,7′-di-2-thienyl-2′,1′,3′-benzothiadiazole)]

is a polymer with high photoelectric efficiency, which is used as a donor material. It can form mixtures with various conductive polymers that can be used to increase energy conversion efficiency.

Soluble in THF, chloroform, chlorobenzene, dichlorobenzene and 1,2,3-trichlorobenzene

These p-type polymers are used as donor materials, organic photoelectric (OPV) materials, in organic and printed electronics.

Molecular weight characteristics: Mw = 100÷300 kDa, PDI= 1.5÷3
