thermal stability of the compound was investigated by thermogravimetric analysis (TGA). The liquid crystalline behavior was studied by differential scanning calorimetry (DSC), polarizing optical microcopy (POM), and wide‐angle X‐ray diffraction (WAXD) measurement. These investigations have shown that the supramolecular structure of H6B‐β‐CD are consisted of a large scale ordered lamellar structure and a
定义明确的结构液晶庚基[6-脱氧-6-(1-H-1,2,3-三唑-4-基)(甲基)6-(4-甲氧基联苯-4'-基氧基)己酰基]- β-环糊精(H6B-β-CD)是由炔丙基6-(4-甲氧基联苯-4'-基氧基)己酸(P6B)和庚基(6-脱氧-6-叠氮基)-β-环糊精((N 3))合成的7 -β-CD)点击反应。H6B-β-CD的化学结构由1确定1 H NMR,FTIR和MALDI-TOF MS 通过热重分析(TGA)研究了该化合物的热稳定性。通过差示扫描量热法(DSC),偏振光学显微镜(POM)和广角X射线衍射(WAXD)测量研究了液晶行为。这些研究表明,H6B-β-CD的超分子结构由低温区域的大型有序层状结构和小规模有序结构(SmE)组成。随着温度的升高,小规模结构首先从近晶E到近晶A变得相对无序。然后,层状结构塌陷,依次观察到向列相和各向同性相。©2010 Wiley Periodicals,Inc
