Unconventionally modified dibenzoylmethane (dbm) ligands have been synthesized and successfully utilized as ancillary ligands for neutral Ir(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.
