  The present invention concerns functionalized photoreactive compounds of formula (I), that are particularly useful in materials for the alignment of liquid crystals. Due to the adjunction of an electron withdrawing group to specific molecular systems bearing an unsaturation directly attached to two unsaturated ring systems, exceptionally high photosensitivities, excellent alignment properties as well as good mechanical robustness could be achieved in materials comprising said functionalized photoreactive compounds of the invention.

  本发明涉及式(I)的官能化光反应化合物，特别适用于液晶对准材料。由于在特定分子系统中的不饱和键直接连接到两个不饱和环系统上附加了一个电子受体基团，因此在包含本发明的这些官能化光反应化合物的材料中可以实现异常高的光敏性、优异的对准性能以及良好的机械稳健性。

  Disclosed is a graded index type optical fiber having a multilayer structure comprising a plurality of concentrically arranged non-blended layers LNB1 to LNBm formed of (co)polymers P1 to Pm selected from the group consisting of two or more homopolymers HP1, HP2, ... and HPn composed of units of vinyl monomers M1, M2, ... and Mn, respectively (provided that the refractive indices of the homopolymers decrease in that order), and one or more binary copolymers CPs composed of units of vinyl monomers M1, M2, ... and Mn, each of (co)polymers P1 to Pm having a glass transition temperature (Tg) of 80°C or above, wherein the refractive index is highest at the center of the multilayer structure and decreases gradually toward the outer periphery thereof. This optical fiber has a small transmission loss, a large numerical aperture, and excellent resistance to moist heat.
