    • 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 formula wherein 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; and m 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; and m is an integer from 0 to 2.
