title: Synthesis of sterically crowded polyarylated boron-dipyrromethenes.
abstract: A rapid synthetic route for polyarylated boron-dipyrromethenes using hexabromo boron-dipyrromethene as the key synthon is described. The X-ray structure revealed that the polyarylated BODIPY adopts a propeller-like conformation. These compounds exhibit red-shifted absorption and fluorescence bands with decent quantum yields and reversible oxidation and reduction waves when compared to unsubstituted boron-dipyrromethenes.
