failed to form an organogel in the selected solvents, revealing that tert-butyl played an important role in gel formation. X-ray diffraction patterns of xerogels indicated that TCBT molecules self-assembled into a lamellar structure in the gel state. In particular, xerogel-based films of TCBT emitted strong blue light and could be used as fluorescent sensory materials to detect acid vapors of TFA, HCl,
合成了两种新的苯并噻唑改性的咔唑衍生物(CBT和TCBT)。发现具有叔丁基部分的TCBT可以在超声刺激下使环己烷,环戊醇和辛烷/环己烷(v / v = 2/1)凝胶化,但是没有叔丁基的CBT不能在选定的溶剂中形成有机凝胶,表明叔丁基在凝胶形成中起重要作用。干凝胶的X射线衍射图表明,TCBT分子在凝胶状态下自组装成层状结构。尤其是基于干凝胶的TCBT薄膜由于分析物在包含许多纳米纤维的3D网络中具有良好的吸附和扩散性能,因此可发出高性能的蓝光,并可用作荧光传感材料,可高效检测TFA,HCl,HNO 3,甲酸和乙酸中的酸蒸气。以及纳米纤维中的有效激子迁移。这表明π-胶凝剂的有机胶凝是产生高效化学传感器的简便方法。
