The syntheses and physicochemical properties for a series of 2,6-disubstituted-4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) dyes are reported. The use of chromophores or redox active species as π-spacers, such as BODIPY, requires the inclusion of a sufficiently conjugated donor in order to achieve appropriate charge separation upon photoexcitation. The information derived from this study offers guiding principles for incorporating strongly absorbing, non-innocent π-spacers in organic dye design.
本文报道了一系列 2,6-二取代-4,4-二氟-4-硼-3a,4a-二氮杂-s-茚满（BODIPY）染料的合成及理化性质。将发色团或氧化还原活性物质作为π-间隔基（如 BODIPY）使用时，需要包含足够的共轭供体，以便在光激发时实现适当的电荷分离。该研究提供的信息为在有机染料设计中引入强吸收、非中性π-间隔基提供了指导原则。
