elucidated. TAEs have widespread applications in material science and supramolecular chemistry due to their aggregation‐induced emission (AIE) properties. The divergent and stereoselective synthesis of [3+1]‐, [2+2]‐, and [2+1+1]‐TAEs via multiple couplings of vinylboronates with aryl bromides is demonstrated. These couplings feature a broad substrate scope and excellent functional group compatibility
