A series of β-diketone-boron difluoride derivatives bearing different methyl-substituted phenyl groups were designed and synthesized, and two of these boron-difluorides could form stable organogels in non-polar solvents, demonstrating that the methyl substituents have a significant effect on their gelation ability. Through temperature-dependent ¹H NMR and photophysical properties analysis, we deemed that intermolecular non-covalent interactions facilitate the one-dimensional packing. Moreover, superhydrophobic surfaces, characterized by water contact angles around 150° could be obtained by means of the gelation of these boron-difluoride dyes. Thus, our work provided a unique example for designing non-conventional organogelators with superhydrophobic surfaces by introducing methyl-substituted phenyl groups into β-diketone-boron difluoride skeleton.

设计并合成了一系列带有不同甲基取代苯基的β-二酮-硼二氟化物衍生物，其中的两个二硼化硼可以在非极性溶剂中形成稳定的有机凝胶，表明甲基取代基对其取代有重要影响。胶凝能力。取决于温度¹通过1 H NMR和光物理性质分析，我们认为分子间非共价相互作用促进了一维堆积。此外，借助于这些二氟化硼染料的凝胶化，可以获得以150°左右的水接触角为特征的超疏水表面。因此，我们的工作提供了一个独特的实例，可以通过将甲基取代的苯基引入β-二酮-硼二氟化物骨架中来设计具有超疏水表面的非常规有机胶凝剂。
