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

Abstract

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 C₂-chiral polymers form amorphous thin films on HOPG and exhibit good chirality-induced spin selectivity with spin polarization of nearly 70%.
