We report the results of a detailed study of the nonlinear optical properties of a dithiolene (Ni-bis(1-phenyl-2-butyl- 1,2-dithiolene)) and a diimine (Pt-bis(diaminomalenonitrile)). The aim of this study was to discern the relative importance of electronic and thermal contributions to the nonlinear susceptibility of the dithiolenes and diimines. We find that the nonlinear optical response of these materials is dominated by thermal mechanisms and that the electronic contribution to the nonlinearity of these materials is rather small.
