Helically chiral boron chelated dipyrromethenes showed solution phase circularly polarized luminescence (CPL) in the red region of the visible spectrum. Desymmetrisation of the parent BODIPYs can be achieved through <i>O</i> chelation of the central boron atom by one or more <i>ortho </i>phenolic substituents at the 3/5 positions. The resulting helical perturbation of the fluorophore resulting in CPL with high luminescence dissymmetry factors and fluorescence quantum yields. In this presentation, we will both advances in molecular design, leading to improved CPL efficiencies, as well as novel synthetic approaches for enantioselective synthesis of helically chiral BODIPYs.
