2000年,艾伦 黑格等人因为发现了导电聚合物被授予诺贝尔化学奖,开拓了有机电子学的新时代,在各种电子器件中,诸如场效应晶体管、太阳能电池、电致发光、存储、传感、激光器等,有机材料都相继出现并被证明有广阔的应用前景。因此,对材料、器件、物理等领域的全面理解和掌握,对有机电子学的发展十分必要。本门课程首先从有机光电材料的性质与化学结构关系出发,对有机材料的光学和电学性质作了详细的论述;阐释了相关概念和机理,并介绍了重要的表征方法;本门课程还介绍了有机光电材料的重要应用,如有机场效应晶体管、有机太阳能电池、有机电致发光等。在本课程中,我们将重点学习有机材料的基本概念和器件的工作机制。
通过本课程的学习,要求学生全面掌握以有机材料为基础的光电功能材料特性及其本质,同时对有机光电功能材料的器件应用。
