6‐bis(iminopyrrolyl)‐anthracenyl]BPh2 (15)) and the star‐shaped triboron complex ([4′,4′′,4′′′‐tris(iminopyrrolyl)‐1,3,5‐triphenylbenzene](BPh2)3 (16)) were obtained in moderate to good yields, by the treatment of 3–9 with B(C6H5)3. The ligand precursors are non‐emissive, whereas most of their boron complexes are highly fluorescent; their emission color depends on the π‐conjugation length. The photophysical properties
