摘要:
合成一种在咪唑环C-2上不含酸性质子的新型离子液体,六氟磷酸1,2-二甲基-3-十六烷基咪唑.采用偏光显微镜(polarizing optical microscope,POM)、示差扫描量热法(differential scanning calorimetry,DSC)和变温型广角X-射线衍射(wide X-ray diffraction,WXRD)等研究其热致液晶行为,研究该离子液体的液晶结构和自组装过程.结果显示,该疏水性离子液体在加热和冷却过程中呈双向热致液晶行为,存在固-固、固-液晶和液晶-液态3个相转变,其层间距和半峰宽均与温度相关.
Abstract:
A new imidazolium-type ionic liquid(IL)1,a 2-dimethyl-3-hexadecylimidazolium hexafluorophosphate, lacking acidic proton at the C-2 imidazolium ring position,was synthesized, and its thermotropic liquid crystalline phase behavior was studied.The structure of liquid crystal and self-assembly process of the IL molecules were also studied.The insoluble IL exhibits bidirectional thermotropic liquid crystalline on heating and cooling. There exists phase transitions,namely,solid-solid,solid-mesophase,mesophase-isotropic phase.The layer spacing and the full widths at half-maximum from X-ray diffraction(XRD)patterns display temperature dependence.
