    摘要: The invention pertains to an isosorbide derivative having at least one polymerizable group, characterized in that the isosorbide derivative further comprises at least one photo-convertible group for adjusting the helical twisting power of the isosorbide derivative. According to a preferred embodiment the isosorbide has the formula wherein A stands for a bond or a p-phenylene group; B and B′ are independently O—(CH2)oO—CO—CR′═CH2, o being 2-12 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.
