摘　　要：有机太阳能电池因具有质轻、柔性及可印刷制备等优点而受到广泛关注.调控和优化金属电极与有机半导体活性层之间的软/硬材料界面是有机太阳能电池界面工程的前沿课题,其核心是新型界面材料的设计合成与器件集成.紫罗烯聚合物是一类新兴的非共轭聚合物电解质界面材料,其离子部分位于聚合物主链.相对于传统共轭聚合物电解质,紫罗烯聚合物合成方法简单,条件温和而且绿色,具有更高的离子浓度和更强的界面诱导极化能力,适用于有机太阳能电池的界面修饰.电活性紫罗烯的最新研究进展激发了科研人员探索这种新型聚合物在有机电子器件中应用的兴趣.本综合评述介绍了电活性紫罗烯聚合物的分子设计与合成,讨论了紫罗烯聚合物修饰金属电极的机理和作用,以及其电荷传输性能和界面能级调控能力.Organic solar cells have attracted wide attention from academia and industry due to their advantages of light weight,flexibility,and printable preparation.The modulation and optimization of the soft/hard material interfaces between metal electrodes and organic semiconductor active layers is the research frontier of interface engineering in organic solar cells.The core of the research is the design and synthesis of new interlayer materials and their integration into devices.Ionene is an emerging class of non-conjugated polyelectrolytes-based interlayer materials,in which ionic species reside within the polymer backbone.Compared with traditional conjugated polyelec-trolytes,the synthesis of ionene polymers is simple,the reaction conditions are mild and green,and it has higher ion concentration and stronger interfacial polarization capability,which is suitable for the interface modification of organic solar cells.Recent advances in electroactive ionene have stimulated the interest of researchers to explore the application of this novel polymer in organic electronic devices.In this review,the molecular design and synthesis of electroactive ionene polymers were reviewed,and the mechanism and function of these ionene polymers on interfacial modifications were discussed,as well as their charge transport property and the performance of interfacial energy level alignment.
