“General Chemistry”是面向中外合作办学工科专业学生开设的一门学科基础课。为了提升教学质量，课程引入国外经典教材，在教学过程中面临外来文化的冲击和文化自信缺失的风险。因此，必须通过“General Chemistry”课程思政教学提升学生对自身文化的深度认同。本文中，“General Chemistry”课程思政建设坚持文化自信理念，积极挖掘中国思政元素，将中外思政元素合理融入到教学的每一个环节，不断助推课程思政教学内涵式发展，打造课程思政高效课堂，取得了较好的育人成效。

针对高分子化学本科教学中“活性自由基聚合”知识点抽象，学生难以理解的教学难题，开展了光引发可逆加成断裂链转移(RAFT)自由基聚合3D打印实验。实验首先合成O-(乙基)-S-(2-丙酸乙酯基)黄原酸酯(EXEP)，随后使用商用光敏树脂，进行添加/不添加EXEP条件下的3D打印。随后使用得到的打印体开展荧光功能后修饰与焊接对比实验。通过对比实验现象，深入理解活性自由基聚合机理及其对产物后功能化能力的影响，实现“活性自由基聚合”原理的“可视化”和实例化应用展示。本实验将基础理论有机融合到趣味实验中，实验耗时合理，操作简便，效果明显，符合本科教学实验基本要求，有助于提升学生综合分析能力，激发学生深入研究的兴趣，培养其创新意识及拓展延伸的能力。

We report a robust pillar-layered metal-organic framework, Zn-tfbdc-dabco (tfbdc: tetrafluoroterephthalate, dabco: 1, 4-diazabicyclo[2.2.2]octane), featuring the fluorinated pore environment, for the preferential binding of propane over propylene and thus highly inverse selective separation of propane/propylene mixture. The inverse propane-selective performance of Zn-tfbdc-dabco for the propane/propylene separation was validated by single-component gas adsorption isotherms, isosteric enthalpy of adsorption calculations, ideal adsorbed solution theory calculations, along with the breakthrough experiment. The customized fluorinated networks served as a propane-trap to form more interactions with the exposed hydrogen atoms of propane, as unveiled by the simulation studies at the molecular level. With the advantage of inverse propane-selective adsorption behavior, high adsorption capacity, good cycling stability, and low isosteric enthalpy of adsorption, Zn-tfbdc-dabco can be a promising candidate adsorbent for the challenging propane/propylene separation to realize one-step purification of the target propylene substance.
