Description	Solvent effects on the electronic absorption spectra of donor-substituted 11,11,12,12-tetracyano-9,10-anthraquinodimethanes (TCAQs) 1?3 have been investigated in 32 well-selected solvents. These compounds were chosen as model structures for charge-transfer chromophores featuring second- and third-order nonlinear optical properties. The resulting data were evaluated by means of theoretical models and (semi)empirical correlations determining the optical properties related to electron distribution and polarizability.We found that solvent effects on a polar D-p-A system do not depend on the donor/acceptor orientation (HOMO/LUMO localization) but especially on the length of the p-system in between. The observed solvent effects are described with high accuracy by the applied theoretical models and linear combinations of physical quantities. Solvent polarization, permanent dipole moment, and molar volume substantially affect the longest-wavelength absorption maxima.
