BODIPY (4,4-difluoro-4-bora-3a,4a-diaza-s-indacenes) dyes possess intense absorption profiles that can be exploited in various light harvesting applications. However, redox stability and optimization of frontier molecular orbital energies in these dyes are critical for their successful incorporation into new solar cell materials. This article describes the synthesis and characterization of a family of β-substituted BODIPY-ferrocene dyads with push-pull architectures. Designed to stabilize the photo-oxidized BODIPY for dye-sensitized solar cell (DSSC) applications, some deleterious electron transfer behaviours emerged when the ferrocene unit was conjugated to electron deficient BODIPYs. These findings are discussed herein.
BODIPY(4,4-二氟-4-硼-3a,4a-二氮杂-s-茚)染料具有强烈的吸收光谱,可用于各种光捕获应用。然而,这些染料的氧化还原稳定性和前沿分子轨道能量的优化对于将它们成功整合到新型太阳能电池材料中至关重要。本文描述了一系列具有推拉结构的β-取代BODIPY-二茂铁二元化合物的合成与表征。设计这些化合物是为了稳定用于染料敏化太阳能电池(DSSC)应用的光氧化BODIPY,但当二茂铁单元与缺电子的BODIPY共轭时,出现了一些有害的电子转移行为。本文将讨论这些发现。
