A new triarylborane–aza‐BODIPY conjugate is reported. The compound consists of two blue emissive dimesitylarylborane moieties and a near‐infrared (NIR) emissive aza‐BOIDPY core and shows panchromatic absorption spanning approximately 300–800 nm. DFT computational studies suggest limited electronic communication between the individual fluorophore units. Hence, the partial energy transfer from blue fluorophore triarylborane to NIR chromophore aza‐BODIPY unit leads to a broad dual‐emissive feature covering a large part of visible and NIR region. Furthermore, the broadband emissive compound can act as a selective sensor for fluoride anion as a result of fluorescence quenching response in both visible and NIR spectral regions.
