Reaction with #boron trifluoride leads to the corresponding #aza-BODIPYs, induces a stereochemical inversion that destroys the helix, flattens the system and switches on #fluorescence.

We report aza-dibenzodipyrromethenes with an interesting architecture where the core adopts a helical arrangement, placing terminal aromatic fragments directly on top of each other in close, p-stacked arrangement. Symmetrical and unsymmetrical derivatives can be afforded with a controlled approach.
