Because BF is a labile, non- or weakly coordinating anion, it is generally chosen by chemists who do not want the anion to interfere with the associated cation. Herein, we demonstrate that BF actually strongly binds to triazole-appended dipyrromethenes (TADs). In particular, HETCOR NMR experiments and DFT calculations were used to rationalize the results observed with anion titrations. Hence, special care should be taken when considering that BF is innocent.

由于 BF 是一种不稳定、非配位或弱配位的阴离子，因此通常被那些不希望阴离子干扰与之结合的阳离子的化学家所选择。在这里，我们证明 BF 实际上与三唑取代的二吡咯甲烷（TADs）强烈结合。具体来说，使用 HETCOR NMR 实验和 DFT 计算来推断与阴离子滴定观察到的结果。因此，在考虑 BF 是“无辜的”时，应该特别小心。
