Shine bright like a dAIEmond ! A series of new O,O‐chelated boron complexes has been prepared through a four‐component Ugi reaction followed by the complexation of the resulting 1,3‐dicarbonyl compounds with boron trifluoride diethyl etherate. The optical properties of these novel luminophores have been assessed, revealing pronounced aggregation‐induced emission (AIE) features. The photoluminescence quantum yields for the solid samples were observed in the range of about 0.80–1.00, placing them among the most efficient boron‐based luminophores.
