| 摘 要： | 近来对由不相容部分构成的块状共聚物的研究表明,通过改变各块的对比度(刚性与柔性,亲水性与亲油性,极性与非极性等)或改变各块的相对体积比, 均可改变这类物质的自组装行为获得新的液晶相态1a].

| Abstract: | Several starlike low-aspect-ratio block molecues were synthesized in this article.They are tetrahedral pentraerytritol esters(5 and 9) which are synthesized via esterification of pentraerytritol with corresponding carbonic acid;and tetraphenylmethane derivatives 16,17,which are synthesized from the corresponding tetraiodide by suzuki coupling reaction as key step.Based on the investigation of polarizing optical microscopy and differential scanning calorimetry,the mesophase behavior of these compounds are analysed,they show no liquid crystalline behaviors and the reason was given. |
