AbstractA new chiral conjugated polymer was synthesized by the Wittig-Horner polymerization of optically active binaphthyl monomer at the 3, 3'-positions. The circular dichroism spectrum of the polymer shows that the degree of circular polarization,in absorption, g(abs), is 1. 9 x 10(-3) in chloroform at room temperature. The circularly polarized photoluminescence spectrum of the polymer shows that the degree of circular polarization in-emission, g(lum), is -1. 6 x 10(-3) in chloroform at room temperature. As the polymer is readily soluble in chloroform, the results, indicate that the circular polarization in absorption and emission is originated from molecularly dissolved, chains and is due to exciton coupling between chain segments of the same polymer molecule. The results also show that the polymer could emit partially circularly polarized light when irradiated. in chloroform,at room temperature.
