A series of fused 4,5‐borazaropyrrolo[1,2‐a]quinolines have been prepared from potassium organotrifluoroborates and substituted 1‐(2‐aminophenyl)pyrroles via direct formation of C–B and N–B bonds. The target products were obtained in moderate to high yields under mild conditions. The optical properties of some products were investigated by UV/Vis spectroscopy and spectrofluorometry. Moreover, the influence of structural modification on the spectroscopic and electronic properties was studied by DFT calculations. A new B‐containing heterocyclic compound! A series of azaborines were prepared through 1‐(2‐aminophenyl)pyrroles and organotrifluoroborates in a one‐pot reaction. The optical properties of these azaborines were investigated and the attractive photometrics could be applied in many scientific fields.
