本文评价了二芳基（甲烷）二氟化硼化合物在设计高效双光子吸收荧光探针中的应用。三种不同的途径允许合成对称和不对称分子被报道。稳定的二芳基（甲烷）二氟化硼衍生物很容易得到，产率高。它们表现出很大的单光子吸收，很容易在近紫外范围内调谐。它们强烈的荧光发射覆盖了整个可见域。除了这些吸引人的线性性质外，一些二芳基（甲烷）二氟化硼衍生物具有显著的双光子吸收截面。推导出的结构-性能关系为设计依赖二芳基（甲烷）二氟化硼骨架的新一代分子提供了希望。
This paper evaluates the use of diaroyl(methanato)boron difluoride compounds for designing efficient fluorescent probes through two-photon absorption. Three different pathways allowing for the syntheses of symmetrical and dissymmetrical molecules are reported. The stable diaroyl(methanato)boron difluoride derivatives can be easily obtained in good yields. They exhibit a large one-photon absorption that is easily tuned in the near-UV range. Their strong fluorescence emission covers the whole visible domain. In addition to these attractive linear properties, several diaroyl(methanato)boron difluoride derivatives possess significant cross sections for two-photon absorption. The derived structure-property relationships are promising for designing new generations of molecules relying on the diaroyl(methanato)boron difluoride backbone.
