Tuning the Physicochemical Properties of BODIPY for Bioimaging via meso -Amino Acylation.

A series of BODIPY probes with a wide emission range were prepared via aminoacylation at the meso -position. Functional moieties were also introduced to induce bathochromic shifts in emission, improve water solubility, increase Stokes shifts, and construct bioorthogonal turn-on probes. The developed analogues were successfully used in live-cell imaging, suggesting that the described strategy can be used to prepare probes with improved bioimaging potential.
