Kamlet-Taft solvent parameters of selected solvents were determined according to a previously reported method , using a UV-Vis spectrophotometer (Evolution 201, Thermo Scientific, Waltham, MA, US) scanning from 300 to 700 nm at 0.5 nm intervals and quartz cuvettes with 1 mm light path. Alternatively, parameters were taken from a previous report using the same method for determination . The Kamlet-Taft values express the relative strength of different solvent interactions, with 0.0 representing weak/no interactions and 1.0 and higher representing strong interactions.
