Fluorescence-based materials and associated techniques (analytical, imaging, and sensing techniques) have been highlighted over the last century throughout various basic research fields and industries. Organic molecule-based fluorophores, in particular, have ushered in a new era in biology and materials science. To date, hundreds of organic fluorophores have been developed, and many studies have introduced new rationales for the fluorophore design and the analysis of the relationship between its structure and photophysical properties both in the solution- and solid-state. In this review, we summarize the recent advances (mainly from 2015 to 2020) in single-benzene-based fluorophores (SBBFs), which have an electron-donor (D)-acceptor (A) type dipolar structure within a compact benzene backbone. We also present a systematic outline of the physicochemical properties of SBBFs and representative examples of their applications, which will provide useful context for the development of new SBBF derivatives in fluorophore-related materials science fields.
基于荧光的材料和相关技术（分析、成像和传感技术）在过去一个世纪中在各个基础研究领域和工业中得到了突出的发展。特别是基于有机分子的荧光团开创了生物学和材料科学的新时代。迄今为止，已经开发了数百种有机荧光团，并且许多研究都提出了新的荧光团设计原理，以及分析其结构与光物理性质之间的关系，无论是在溶液中还是在固态中。在这篇综述中，我们总结了单苯基荧光团（SBBFs）的最新进展（主要是 2015 年至 2020 年），这些荧光团在紧凑的苯环骨架内具有电子给体（D）-受体（A）型偶极子结构。我们还系统地概述了 SBBFs 的物理化学性质和它们在代表性应用中的实例，这将为相关材料科学领域中新型 SBBF 衍生物的发展提供有用的背景信息。
