Asymmetric boron complexes composed of (iso)quinolyl-pyrrole ligands possessing a triphenylamine unit on the (iso)quinoline or pyrrole moieties were systematically prepared. Their optical properties were investigated in various organic solvents, and they showed solvatochromic properties, which were influenced by the π-structure of the ligands and the position of the electron-donor group. The degrees of changes in the emission color changed significantly between regioisomeric chromophores 1 and 2. In this study, the solvatochromic properties of the compounds were investigated and described using both experimental and computational results.
