摘要： An optically active compound of the following general formula (1), 1 wherein A is nullCnullCnull or nullCOOnull, each of R1 and R2 is independently CnH2nnull1null, (C2H5)2CHCH2C*H(CH3)OOCnull, CmH2mnull1C*H(CH3)OOCnull or C6H5C*H(CH3)OOCnull in which n is an integer of 2 to 5, m is an integer of 5 to 9, C6H5null is phenyl group, and C* is an asymmetric carbon, provided that there is no case where R1 and R2 are together CnH2nnull1null or C6H5C*H(CH3)OOCnull and that when both R1 and R2 are CmH2mnull1C*H(CH3)OOCnull, m in CmH2mnull1C*H(CH3)OOCnull represented by R1 and m in CmH2mnull1C*H(CH3)OOCnull represented by R2 may be different integers. The optically active compound of the present invention is excellently valuable as a chiral dopant since it has properties that its helical twisting power (HTP) is at least 9, that a helical pitch induced decreases with an increase in temperature and further that its birefringence (nulln) is large.
