Unconventionally modified dibenzoylmethane ( dbm ) ligands have been synthesized and successfully utilized as ancillary ligands for neutral iridium(III) complexes of the formula [Ir(dFppy) 2 (LX)], where dFppyH is 2‐(2,4‐difluorophenyl)pyridine and LX is tribenzoylmethane ( tbm ) or 1‐phenyl‐3‐(4‐(pyridin‐2‐yl)phenyl)propane‐1,3‐dione ( pydbm ). The modification of the ligands aims to prevent or enhance possible intermolecular interactions between the dFppy and/or the LX moiety in comparison with the previously reported [Ir(dFppy) 2 ( dbm )] complex. The aggregation induced emission (AIE) properties of these complexes are significantly modulated, as a consequence of the different π–π interactions revealed by X‐ray crystallography.
