摘要：

物理化学实验为各大高校本科化学教学的主干实验课程之一。虽然各高校的物理化学实验内容已十分丰富，但仍然缺乏将不同章节知识点融会贯通以及与学科前沿密切联系的综合型实验内容。我们根据南开大学郭东升教授课题组发表的一篇有关联二炔程序性响应检测胆碱酯酶的工作设计了“联二炔囊泡的光致聚合、热致变色及应用”的物理化学实验，涉及到联二炔缔合胶体的制备、联二炔的紫外光致聚合反应和聚联二炔的热致变色，进而显示其在防伪领域的潜在应用价值。希望通过此实验，使学生对物理化学中的缔合胶体、光化学、热力学、动力学等章节有更深一步的贯通性掌握，并了解自组装、光聚合、变色材料和防伪等相关研究领域的前沿动态。

Abstract:

"Physical chemistry experiments" is one of the most important undergraduate chemistry experiment courses in many universities. Comprehensive as they are, these courses suffer from a drawback of lacking an experiment that connects the knowledge between different chapters and to the frontier research of the chemical society. Inspired by a published work of Prof. Dongsheng Guo's group concerning the detection and imaging of cholinesterase using a sequentially activated diacetylene probe, we designed a physical chemistry experiment of "The photopolymerization, thermochromism and application of diacetylene vesicle". We focused on the preparation of diacetylene vesicle, the photopolymerization of diacetylene, the thermochromism of polydiacetylene, and further explored the experiment's potential application on the anti-forgery technology. We hope that by performing this experiment, students can have deeper understanding of different fields of physical chemistry, such as colloid, photochemistry, thermodynamics, dynamics etc., and can know more about current chemistry research on self-assembly, photopolymerization, chromogenic materials, anti-forgery, etc.
