一种有机凝胶因子对二氧化碳可视化传感的综合实验设计

Design of a Comprehensive Experiment for the Visual Sensing of CO_(2) Using a Synthetic Organogelator

合成了一种萘酰亚胺衍生的有机凝胶因子,测试了其二甲基亚砜(DMSO)凝胶在氟离子诱导下形成的溶液对气流和空气中二氧化碳可视化传感的能力。实验涉及有机合成、性能测试和仪器分析等基本操作,并利用理论知识对分子传感机理进行分析,可以培养学生多种实验技能的综合运用能力和独立分析能力。

A naphthalimide-derived organogelator was synthesized.The solution derived from the stimuli of fluoride ions to the DMSO gel were found to allow a naked-eye sensing of CO_(2) stream as well as CO_(2) in air.The experiment involves some fundamental processes including organic synthesis,property tests,and instrumental analysis.The sensing mechanism was investigated using the theoretical knowledge.It is possibly helpful to cultivate students comprehensive application ability and independent analysis ability of various experimental skills.
