The invention pertains to a phenylethanediol derivative having at least one polymerizable group, characterized in that the phenylethanediol derivative further comprises at least one photo-convertible group for adjusting the helical twisting power of the phenylethanediol derivative. According to a preferred embodiment the phenylethanediol has the formulawherein A stands for a bond or a p-phenylene group; B and B' are independently (O)p-CoH2o-O-CO-CR'=CH2, o being 2-12, p being 0 or 1, and R' being H or CH3; P stands for a CH2 or a C=O group; Q and Q' are independently selected from H, C1-C3 alkyl, C1-C3 alkoxy, halogen, and CN;n is an integer from 1 to 3; andm is an integer from 0 to 2; and:wherein A stands for a bond or a p-phenylene group; B is (O)p-CoH2o-O-CO-CR'=CH2, o being 2-12, p is 1, and R' being H or CH3; P stands for a CH2 or a C=O group; Q is selected from H, C1-C3 alkyl, C1-C3 alkoxy, halogen, and CN; andm is an integer from 0 to 2.
