Abstract
Recent synthetic achievements have led to 4,4-disubstituted-4-bora-3a,4a-diaza-s-indacenes (BODIPYs) with varying substituents at the meso, pyrrolic and/or boron sites, with each influencing photophysical properties and utility. This Feature article gives an overview of chemistry at the boron atom in BODIPYs, highlighting our contributions that evolved from synthetic curiosities and now offer this dipyrrolic skeleton potential across a wider range of applications. We first summarise preparative routes to BODIPYs through complexation of boron with the dipyrrinato ligand. The role of boron in protecting dipyrrins is then discussed, followed by strategies by which to achieve facile substitution at the boron atom.

Abstract
A general and robust methodology has been developed for the direct incorporation of a wide variety of C-, N-, P-, O-, S-, and halo-nucleophiles into functional BODIPY conjugates in a single reaction step.

Abstract
Covalent attachment of molecules to metal oxide surfaces typically demands the presence of an anchoring group that in turn requires synthetic steps to introduce. BODIPY (4,4-difluoro-4-bora-3a,4a-diaza-s-indacene) chromophores have long been...

Abstract
F-BODIPYs substituted with BPin functionality have been coupled to aryl halides using a mild and efficient catalyst system involving Pd2(dba)3 and XPhos. The methodology enables the Suzuki–Miyaura cross-coupling of electron-rich, electron-poor, and sterically encumbered BPin-substituted F-BODIPYs to aryl halides bearing various functional groups, thus presenting an opportunity for the preparation of highly functionalised F-BODIPYs without need for the corresponding aryl moiety to be available in borylated form.
