Axially chiral BODIPY DYEmers display intense fluorescence and circularly polarized luminescence (CPL) spectra. Due to exciton coupling between the BODIPY rings the π* states split into two energy levels, giving strong ECD couplets. The strongly emitting excited state is the low‐lying exciton‐coupled level. TD‐DFT and CC2 calculations elucidated the photophysics behind the CPL of these systems. More information can be found in the Full Paper by M. Bröring, L. Di Bari, G. Pescitelli et al. on page 16089 ff.
