The geometry structure, electronic spectra and nonlinear second-order optical properties of 2, 2'-spirobiindan-1, 1', 3, 3'-tetraone and it's derivatives were investigated using AM1 and ZINDO series method. The relationship between the nonlinear second-order optical properties of the studied molecules and their substitutes was studied. The calculated results show that these molecules have high transparence as well as large nonlinear second-order optical susceptibilities.
