| 摘 要： | 本文研究了宾主相互作用的液晶彩色显示盒中二向色性染料的光稳定性。发现宾主盒吸光度的减少几乎正比于暴光时间和强度。经加速寿命试验得到染料的实际寿命,其中若干种蒽醌染料的实际寿命超过十年;在吸光度从A_0(t=0)到0.8A_0范围内,染料在液晶中的有序参数在光照前后几乎不变;探讨了染料分子结构与光稳定性之间的关系。

| Abstract: | The light stability of pleochroic dyes dissolved in liquid crystal colour display cellswith guest-host interactions was investigated. It was found that the decrease of absor-bance of guest-host cell is almost proportional to the exposure time and light intensity.Practical lifetime of dyes was obtained by accelerated life test. The practical lifetime ofsome anthraquinone dyes was found to be longer than 10 years. Order parameter of dyesin liquid crystal of initial and after irradiation is almost not change when absorbancechanges from A_0 to 0. 8 A_0. The relation between the molecular structure and photoche-mical stability of dyes was discussed. |
