In this review we give an overview of the syntheses and photophysical properties of the new class of fluorescent dyes based on a [1,3]-dioxolo[4,5-f]benzodioxole core and their derivatives. Starting from commercially available reactants (e.g., sesamol, 1,2,4,5-tetrachlorobenzene) the core units can be prepared in a simple manner. Then, the benzene core can be derivatized via lithiation and their photophysical properties can be adjusted as desired. The obtained fluorophores have an absorption range of 403–520 nm and an emission range of 495–665 nm. This class of fluorescent dyes is also characterized by a long fluorescence lifetime, a high stability towards photobleaching, large Stokes shifts, and small size. Thus, the DBD dyes are optimally suited for optical sensing.

在这篇综述中，我们概述了基于 [1,3]-dioxolo[4,5- f ]benzodioxole 核心及其衍生物的新型荧光染料的合成和光物理性质。从市售反应物（例如芝麻酚、1,2,4,5-四氯苯）开始，核心单元可以以简单的方式制备。然后，苯核可以通过锂化衍生化，并且可以根据需要调整它们的光物理性质。获得的荧光团具有 403-520 nm 的吸收范围和 495-665 nm 的发射范围。这类荧光染料还具有荧光寿命长、光漂白稳定性高、斯托克斯位移大和尺寸小等特点。因此，DBD 染料最适合光学传感。
