conformational features, ground state polarization, and linear and nonlinear optical properties have been determined experimentally and theoretically, and the results are compared to those of tetrathiafulvalene-related derivatives. The newly prepared compounds show close to optimal bond length alternation values for maximizing the first molecular hyperpolarizability, and one of them displays the highest
合成了具有芳香性1,4-二硫富烯电子供体和很少探索的1,1,3-三氰基-2-苯基丙烯受体的多烯非线性光学(NLO)-团。通过实验和理论确定了它们的构型和构象特征,基态极化以及线性和非线性光学性质,并将结果与四硫富瓦烯相关衍生物进行了比较。新制备的化合物表现出接近最优键长交替的值最大化所述第一分子超极化,并且它们中的一个显示最高μβ 0曾报道为基于dithiafulvene-NLO-phore值。还报道了二硫代富烯基亚甲基转移反应的第一个实例。
