In this study five new compounds, derivatives of 1,3,4-oxadiazole, were synthesized in order to achieve mesomorphic behavior and luminescence. Different types of aliphatic chains were used in order to investigate the influence of alkoxide groups in mesomorphic behavior. All of the compounds showed high thermal stability and strong blue photoluminescence in solution and in solid films. Furthermore,
在这项研究中,合成了五种新化合物,即1,3,4-恶二唑的衍生物,以实现介晶行为和发光。为了研究醇盐基团对介晶行为的影响,使用了不同类型的脂族链。所有这些化合物在溶液和固体膜中均显示出高的热稳定性和强烈的蓝色光致发光。此外,化合物10a – d呈现六方柱状同构,其特征在于偏振光学显微镜和X射线衍射,并观察到强π堆积。值得注意的是,对于两种化合物(10c,d),从各向同性状态冷却至室温后,液晶特性得以保留。这些特性使这些材料成为有机电子产品的理想候选材料。
