We disclose two novel BODIPY dyes, which contain the bulky substituent, [(4-dimesitylboryl)phenyl]ethynyl at 2- and 2,6-positions. The steric bulkiness of the boryl group is effective to suppress the intermolecular interaction in the solid state and thus these two compounds display intense fluorescence not only in solution but also in the solid state. In addition, the BODIPY dyes display sensitive fluorescence responses to fluoride and cyanide anions through the complexation with the boron center of the boryl group and the subsequent decomposition of the BODIPY core, illustrating their potential uses for the fluorescence sensing of fluoride and cyanide ions.
我们公开了两种新型 BODIPY 染料，它们在 2-位和 2,6-位含有庞大的取代基[(4-二甲苯硼基)苯乙炔基]。硼酸酯基团的庞大体积有利于抑制固态中的分子间相互作用，因此这两种化合物不仅在溶液中，而且在固态中都显示出强烈的荧光。此外，BODIPY 染料通过与硼酸酯基团的硼中心的络合以及随后的 BODIPY 核心的分解，对氟离子和氰离子阴离子表现出灵敏的荧光响应，这表明它们有可能用于氟离子和氰离子的荧光传感。
