In this study, a series of symmetrically arylated BODIPY dyes were synthesized using a pre-functionalization method, and their structures were characterized by several spectroscopic methods. The relationship between the aryl substitution pattern and the photophysical and electrochemical properties of the dyes was investigated using experimental and computational methods. It was found that electron-donating
本研究采用预功能化方法合成了一系列对称芳基化的BODIPY染料,并通过多种光谱方法对其结构进行了表征。使用实验和计算方法研究了芳基取代模式与染料的光物理和电化学性质之间的关系。研究发现,中间位置的给电子π共轭基团和C3/C5位置的受电子π共轭基团导致光谱蓝移,而相反的取代模式导致光谱红移。此外,内消旋位置的感应给电子烷基产生蓝色光谱位移,并且内消旋位置的烷基产生蓝色光谱位移。与芳基化对应物相比,该位置显着增加了荧光量子产率。计算研究表明,C3/C5 位置上的茴香硫基基团导致带隙明显变窄。这些结果为新型 BODIPY 染料的设计和开发提供了宝贵的见解,这些染料具有适合各种应用的定制特性。
