摘　　要：基于高等学校化学实验构建基础实验-综合实验-研究性实验教学体系的要求,将科研前沿与本科化学实验教学相结合,设计了一个“苝酰亚胺-氧化剂新型电化学体系检测多巴胺”综合实验,使学生知识系统化,培养学生的科研素养。该实验中,氧化剂K_(2)S_(2)O_(8)对苝酰亚胺超分子材料的电化学还原催化增强作用不是传统电化学实验中单一的电化学过程,而是电化学还原-化学氧化双过程。它的引入可以帮助学生深刻理解电化学体系,强力提高学生解决复杂问题的能力。该实验涉及材料,生命科学,医学等多个学科,能大幅开阔学生的视野,有效提升学生的自我价值感。To response the requirement of constructing the basic experiments-comprehensive experiments-research-oriented experiment teaching system for chemical experiment in university,research frontier was connected with undergraduate chemistry laboratory teaching to design a comprehensive experiment of"perylene diimide-oxidant novel electrochemistry system for dopamine detection",which helped student to systematize their knowledge and cultivate students´scientific literacy.In this experiment,the catalytic enhancement effect of the oxidant K_(2)S_(2)O_(8) on the electrochemical reduction of perylene diimide supramolecular materials was not a single electrochemical process as that in traditional electrochemistry experiment,but electrochemical-chemical oxidation dual processes.Its introduction helped student deeply understand the electrochemistry system,strongly improve the ability to solve the complex problems.And this experiment involved multiple disciplines such as materials,life sciences,medicine,which could broaden students´horizons and effectively enhance their sense of self-worth.
