We report two novel functional dyes based on a boron-dipyrromethene (BODIPY) core displaying a panchromatic absorption with an extension to the near-infrared (NIR) range. An innovative synthetic approach for preparing the 2,3,5,6-tetramethyl-BODIPY unit is disclosed, and a versatile way to further functionalize this unit has been developed. The optoelectronic properties of the two dyes were computed by density functional theory modelling (DFT) and characterized through UV-vis spectroscopy and cyclic voltammetry (CV) measurements. Finally, we report preliminary results obtained using these functional dyes as photosensitizers in dye-sensitized solar cells (DSSCs).
我们报道了两种基于硼二吡咯亚甲基（BODIPY）核的新型功能染料，它们具有全色吸收，且吸收范围扩展至近红外（NIR）区域。本文公开了一种制备2,3,5,6-四甲基-BODIPY单元的创新合成方法，并开发了一种对该单元进行进一步功能化的通用方法。通过密度泛函理论建模（DFT）计算了这两种染料的光电性质，并通过紫外-可见光谱和循环伏安法（CV）测量对其进行了表征。最后，我们报告了将这些功能染料用作染料敏化太阳能电池（DSSC）中的光敏剂所获得的初步结果。
