A series of thiophene-based chiral small bandgap π-conjugated polymers was successfully synthesized. Optical properties of the polymers were investigated by using UV-vis, photoluminescence (PL), circular dichroism (CD) spectroscopies, and specific rotation measurements. Especially, the isothianaphthene-thiophene based copolymers display 10-20 nm longer absorption maximum than those of thiophene-thiophene copolymers in the UV-vis. PL measurements demonstrate that the polymer exhibit light emission. CD spectroscopy measurements reveal helical π-stacking structure of the polymers.
