Chiral dopants with a spiro structure for nematic liquid crystals were synthesized from optically active 3,3′- (4H/,4′H)-spirobi(2H- naphtho[l,2-b)]pyran)-6,6′-dicarboxylic acid, and their helical twisting power (HTP) values were evaluated. Chiral dopants having the S configuration induced minus helices in the host nematic liquid crystals. It was found that the novel ester-linked spiro chiral dopants exhibited large molar HTP values. In particular, a chiral dopant with two pyrimidine structures in the side chain moiety showed the highest molar HTP value of 62.1 μm-1mol -1g. In contrast, ether-linked chiral dopants showed relatively small molar HTP values.
