Organic fluorophores with dynamic conformations in the excited state have played a significant role in applications of organic functional dyes. Among them, dihydrophenazine-based dynamic fluorophores involving a photoinduced structural planarization process in the excited state exhibited large Stokes shifts and conformation-dependent multicolor emissions. With the developments of synthetic strategies, precise modifications on dihydrophenazine-based scaffolds have successfully afforded a variety of precise molecular structures of varying sizes and compositions, which have delicately modulated their photophysical properties. Herein, this Perspective summarizes the precise modulations of dihydrophenazine-based dynamic fluorophores, including the development of the synthetic methodologies, and tailor-made molecular models to reveal the luminescence-structure relationships. Insights about the future molecular design and applications are also presented.
具有激发态动态构象的有机荧光团在有机功能染料的应用中发挥了重要作用。其中，基于二氢吩嗪的动态荧光团在激发态涉及光诱导结构平面化过程，表现出大的斯托克斯位移和构象依赖性多色发射。随着合成策略的发展，对基于二氢吩嗪的支架进行精确修饰已成功获得了各种尺寸和组成不同的精确分子结构，这些结构精细地调节了它们的光物理性质。在此，本综述总结了基于二氢吩嗪的动态荧光团的精确调控，包括合成方法的发展以及定制的分子模型以揭示发光-结构关系。还介绍了关于未来分子设计和应用的见解。
