In a newly-published Angewandte Chemie paper, we (in collaboration with Prof. Andrew E. H. Wheatley from Cambridge University) report the synthesis of a series of unique tetrameric chiral-at-metal alkylaluminium anthranilates.
The new aluminium-based anthranilate complexes exhibit photoluminescence quantum yields of up to 100% in the solid state, enabled by their unique electronic structure and non-covalent interactions that stabilize excited states. We also show that subtle ligand modifications were shown to significantly boost emission efficiency, opening new pathways for designing advanced photoactive materials. These findings contribute valuable insight into the still underexplored photochemistry of multinuclear complexes and their potential applications in optoelectronics.
