ABSTRACT In our days, photochromic polymers possessing the liquid crystalline behaviour attract considerable attention of the scientific community due to their functionality and highlighted effects which can be used for opto-electronics and photonics. Herein, the photoorientation processes under the action of the polarised UV (355 nm) and visible (457 nm) light are studied for the amorphousized films of new azobenzene-containing polymethacrylates with different lengths of alkyl spacers and tails (5, 6 and 10 methylene units). The prominent effects of the chemical structure, namely length of the alkyl spacers and tails, as well as wavelength of the excitation light, on the peculiarities of the photoorientation process are demonstrated. Those effects can lead to quite important conclusions concerning possible influence of the microphase separation in polymer films. Graphical abstarct

间隔和烷基尾长对含偶氮苯液晶聚甲基丙烯酸酯非晶化薄膜光取向过程的影响

摘要 在我们这个时代，具有液晶行为的光致变色聚合物由于其功能性和可用于光电子学和光子学的突出效果而引起了科学界的极大关注。在此，研究了具有不同长度的烷基间隔基和尾部（5、6 和 10 亚甲基）的新型含偶氮苯聚甲基丙烯酸酯的非晶化薄膜在偏振紫外（355 nm）和可见光（457 nm）光作用下的光取向过程。单位）。证明了化学结构的显着影响，即烷基间隔和尾部的长度，以及激发光的波长，对光取向过程的特性的显着影响。这些影响可以导致关于聚合物薄膜中微相分离可能影响的非常重要的结论。图形抽象
