摘要：

We measured the third-order susceptibilities chi(ijkl)([3]) of new bisdithiafulvenyl-substituted tetrathiafulvalene, using the degenerate four-wave mixing method. From these measurements we deduced the values of the second-order hyperpolarizabilities gamma and their molecular and electronic contributions. We compared the third-order optical properties of these new extended tetrathiafulvalene derivatives with the properties of acetylenic and ethylenic analogs of tetrathiafulvalene that we studied previously. All organic molecules studied here revealed large third-order nonlinear optical hyperpolarizability. (C) 1998 Optical Society of America.
