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.
