Solvent effects on charge-transfer (CT) transition energy, hv_<CT>, and association constant, Kc, for π-π intermolecular CT complexing were investigated with hexamethylbenzene-p-chloranil, hexamethylbenzene-tetracyanoethylene, and N, N-dimethylaniline-1,3,5-trinitrobenzene systems in various organic solvents. The values of hv_<cr> linearly decreased with an increase in refractive index (n) and its function (n^2-1) / (2n^2+1) with high significance, while log K_c was recognized to have some relations to functions of dielectric constant (D) such as log D, 1/D, and (D-1) / (2D+1) expressed with an parabolic curve exhibiting the minimum K_c value in the solvent with a D of about 6-10. Some discussion was made on these relationships.
