迅速将尖端科学转化为学生的课程是一项具有挑战性的任务。通常情况下，研究性实验过于复杂或昂贵，无法转化为中等或高等教育环境。在这里，我们介绍了一个实验室实验，它将最近开发的波长相关的光化学作用图的研究技术转换为学生可访问的格式。实践性课程结合了光物理学和聚合物化学的各个方面，光物理学需要计算每种不同颜色LED的恒定光子发射，聚合物化学则需要理解机理和定量确定聚合转化。在实践中，学生(I)学习使用光化学反应产生日常材料的领域，(Ii)理解和应用吸收和比尔-兰伯特定律的概念，(Iii)记录和评估光化学作用情节，以及(Iv)批判性地讨论作用和吸收光谱的不同性质，以了解对光化学材料设计的影响。
The prompt transfer of cutting-edge science into students’ curricula is a challenging task. Often research experiments are too complex or expensive to be translated into a secondary or tertiary education setting. Herein, we introduce a laboratory experiment that translates the recently developed research technique of a wavelength dependent, photochemical action plot into a student accessible format. The practical incorporates aspects of photophysics, required to calculate a constant photon emission from each different colored LED, as well as polymer chemistry in understanding the mechanism and quantitatively determining the polymerization conversion. During this practical the students (i) learn about areas where photochemical reactions are used to generate everyday materials, (ii) understand and apply the concepts of absorption and Beer–Lambert’s law, (iii) record and evaluate a photochemical action plot, and (iv) critically discuss the disparate nature of action and absorption spectra to generate an understanding of the implications for photochemical material design.
