A new class of photosensitive compounds generates optical anisotropy comparable to azobenzene systems upon irradiation with linearly polarized light, but, in contrast to these systems, the new photorotor system does not absorb in the visible range. High values of dichroism and birefringence are induced and in the case of LC polymers the light induced order can be amplified by self-organization.
一类新型的光致各向异性化合物在受到线偏振光辐照时会产生与偶氮苯体系相当的各向异性，但与这些体系不同的是，新型的光致转子体系在可见光范围内不吸收。高的二色性和双折射被诱导，并且在 LC 聚合物的情况下，光致有序可以通过自组织进行放大。
