摘要
有机双荧光发射材料具有两个独立的发射带。因其在荧光智能传感、超分辨成像、信息存储等领域的广泛应用而备受关注。综述结合应用实例,概述了两类不同的双荧光发射系统的研究进展,总结和归纳了基于不同设计原理所构筑的双荧光发射系统的特点,并对其环境敏感性的内在本质进行了讨论。最后,分析了目前有机双荧光发射材料在应用中存在的不足,以及开发新型双荧光发射材料所面临的问题,期望进一步推动智能响应性双荧光发射材料的设计和应用的发展。
Organic dual-fluorescence emitters are one of kinds of the materials with two independent emission bands,which have been intensively pursued for the widespread applications,including smart fluorescence sensing,super-resolution biological imaging,and ultrahigh-density optical data storage,etc.In this paper,the research of two types of dual-fluorescence systems,the emission origins of which are individually originated from two separate fluorophores and two correlated emitting states,were reviewed.The characteristics of the fabricated dual-fluorescence systems based on the different principles for various applications were systematically summarized.Moreover,the nature of their sensitivity to the external environmental changes was discussed in detailed.Eventually,the challenges in various application areas was proposed,which might benefit for inspiring the designs of the new unimolecular dual-fluorescence materials with excellent photochemical and photophysical properties.
