Abstract: In this article, we explore the possibility of introducing chirality at different structural levels within boron-threaded BODIPYs. Three strategies were investigated, involving a chiral macrocycle, a stereogenic boron center and an axially chiral BODIPY dimer. In the latter case, double threading through boron coordination was achieved for the first time. The optical and chiroptical properties of the three chiral systems were investigated. While the chiral macrocycle leads to the most pronounced chiroptical response with clear evidence of chirality transfer to the BODIPY, all three architectures display measurable electronic circular dichroism and circularly polarized luminescence. These results demonstrate that chirality can be deliberately positioned at distinct structural levels of threaded BODIPYs, providing a modular platform to investigate the interplay between molecular architecture and chiroptical properties.
