Abstract: | Reaction of the aluminum dialkynyl LAl(CCR)2 (L=N,N‐chelate ligand and R=organic group) with B(C6F5)3 proceeds through an intermediate with Al???η2‐C≡C side‐on coordination to form the alumoles ( 2 , 4 , 6 ). A distinctive reaction pattern indicates a new facile synthetic route to aluminum‐containing heterocycles. The synthetic process is described, and the characterization of compounds and computational calculations were carried out. Furthermore, alumoles 2 and 4 exhibit an aggregation‐induced emission (AIE) of the bright yellow fluorescence. |
