摘要
有机材料的宏观性质是分子聚集效应的客观体现,不仅取决于单个分子的结构,而且与整个分子的聚集形式密切相关.通过对分子聚集态行为的有效调控,科学家们发现了一些完全不同于单个分子特性的聚集态发光现象,包括发光强度、颜色、形式以及激发过程的差异.本文对这些有趣的聚集态发光材料进行了简要的综述,系统分析了分子聚集模式和分子间相互作用对材料发光性能的影响,并介绍了"MUSIC"的理念,以音乐创作形象化材料设计,强调分子聚集态行为的重要性.
“Union is strength”.In the realm of organic molecules,the macroscopic performance of molecular aggregates is not just the simple overlay of single molecules,and in many cases,new properties can be created by molecular uniting with particular packing modes[1–4].As to the organic emissive materials,various changes can be rea-lized from single molecules to aggregates(Fig.1),in-cluding the emerged bright emission,the varied emission color,the different emission forms,and the arisen new excitation processes.
