Chiral bifacial indacenodithiophene-based π-conjugated polymers with chirality-induced spin selectivity.

Novel optically active π-conjugated polymers having a chiral bifacial indacenodithiophene backbone were synthesized by Suzuki-Miyaura cross coupling polymerization with benzothiadiazole comonomer. The obtained C 2 -chiral polymers form amorphous thin films on HOPG and exhibit good chirality-induced spin selectivity with spin polarization of nearly 70%.
