新型螺旋共轭有机分子合成与非线性光学性质

Spiro conjugation is a new kind of conjugation, not like plan conjugation, this kind of conjugation is a three dimensional conjugation. In this project, we investigated the effect of spiro conjugation of 2,2'-spirobiindan-1,1'-dione and it's derivatives. Firstly the geometry structure, electronic spectra and nonlinear second-order optical properties of 2,2'-spirobiindan-1,1'-dione and it's derivatives were investigated using AM1 and ZINDO series method. The relationship between the nonlinear second-order optical properties of studied molecules and their substitutes was studied. On the bases of theoretical study, a part of molecules were synthesized and characterized.
