existing molecular frameworks has resulted in the production of a wide range of multifunctional molecular materials. However, this strategy has not yet been explored for an emerging class of boron difluoride dyes, derived from formazanate ligands, which often exhibit tuneable redox and optical properties. Here, we address this gap in the literature and describe the synthesis and characterization of a
将苯并噻唑杂环结合到现有的分子框架中,产生了广泛的多功能分子材料。然而,这种策略尚未针对一类新兴的二氟化硼染料进行探索,该染料衍生自甲氮酸盐配体,通常表现出可调节的氧化还原和光学特性。在这里,我们解决了文献中的这一空白,并描述了一系列苯并噻唑取代的 BF 2的合成和表征甲酸盐。与三苯基取代的类似物相比,苯并噻唑的加入导致吸收曲线转移到较低的能量和还原事件,转移到更正的电位。这些结果得到了 DFT 和 TD-DFT 计算的证实,这些计算表明苯并噻唑单元的加入导致 LUMO 能级的稳定,从而缩小了这一新系列易于获得的染料的 HOMO-LUMO 间隙。这些参数的微调通过附加到甲氮酸酯配体骨架的支持N-芳基取代基的变化来证明。
