Two series of dibenzophenazines with their mesogenic cores substituted by indent or bulge peripheral side chains have been synthesized. A good balance between anisotropy and isotropy has been achieved by the tri-functionalized bulge-discogen having a pair of interdigitating alkoxy chains. On cooling, the tri-functionalized bulge-discogen with a low melting temperature and high clearing temperature remains liquid crystalline at room temperature.

苯并呋喃的化合物已合成,其介晶核心被凹进或鼓起的外围侧链取代。通过具有一对交错的烷氧基链的三官能化鼓起盘状分子,达到了各向异性和各向同性之间的良好平衡。在降温过程中,具有低熔点和高清除温度的三官能化鼓起盘状分子在室温下仍保持液晶态。
