BODIPY类染料荧光发射及应用

Fluorescence Emission and Application of BODIPY

摘要: BODIPY激光染料是现代光化学研究的一个热门主题，因为它的发色团提供了多种选择，可用于多种合成路线。通过BODIPY染料的取代模式来调节光谱性质或诱导新的光物理过程的可能性增加了这些荧光团的科技应用数量，但直到90年代初，由于Boyer及其同事的先驱工作，BODIPY才成为可调谐染料激光器的活跃媒介。这些染料的最佳激光性能是由于它们的化学稳定性、高耐热性、低光降解性，以及主要是它们独特的光物理特征，这些特征深深地依赖于分子结构，总的来说，这种发色团很容易溶于大多数有机介质，其特征是可见光谱的绿–黄部分具有强吸收和荧光光谱带，荧光效率接近100%，且与周围环境的性质无关。20世纪90年代后，BODIPY作为可调谐激光染料的用途得到了推广并扩展到固态，它们还被应用于许多其他科技领域。

Abstract: BODIPY laser dye is a hot topic in modern photochemical research, because its chromophore provides a variety of options and can be used in a variety of synthetic routes. The possibility of adjusting spectral properties or inducing new photophysical processes through the substitution mode of BODIPY dyes has increased the number of scientific and technological applications of these fluorophores. However, until the early 1990s, due to the pioneering work of Boyer and his colleagues, BODIPY has become the active medium of tunable dye lasers. The best laser performance of these dyes is due to their chemical stability, high heat resistance, low photodegradability, as well as their unique photophysical characteristics. These characteristics are deeply dependent on the molecular structure. In general, this chromophore is easily soluble in most organic media. Its characteristic is that the green-yellow part of the visible spectrum has strong absorption and fluorescence spectral bands, and the fluorescence efficiency is close to 100%. It has nothing to do with the nature of the surrounding environment. After the 1990s, the use of BODIPY as a tunable laser dye has been promoted and extended to solid state. They have also been used in many other scientific and technological fields.
