was synthesized and their UV–Vis absorptionspectra were recorded in the region 200–600 nm in the set of selected solvents. The effects of solvent dipolarity/polarizability and solvent–solute hydrogen-bonding interactions on the spectral shifts were analyzed by means of the linear solvation energy relationship concept of Kamlet and Taft. The influence of solvents as well as substituents on the 2-
