Mesophase forming chromophores are an important challenge of material science. This article describes the synthesis of new perylene mesogenes 10. The materials were obtained by twofold Diels-Alder reactions of our recently published 1:1 isomeric mixture of 3,9- and 3,10-dialkylperylenes with N-heptadecyltriazoline-3,5-diones. In contrast to the analogous derivatives 1 published earlier by our group (see reference 3), the new compounds 10 are prepared by a more efficient synthetic route and on a larger scale. Furthermore the characteristics of the liquid crystalline behavior of both materials are compared.
中相形成发色团是材料科学领域的重要挑战。本文介绍了新型芘中相的合成。这些材料是通过我们最近发表的3,9-和3,10-二烷基芘与N-十七烷基三唑啉-3,5-二酮的1:1异构体混合物的双重Diels-Alder反应获得的。与本研究组之前发表的类似衍生物1(见参考文献3)相比,新化合物10是通过更有效的合成路线和更大规模制备的。此外,两种材料的液晶行为特征进行了比较。
