我们成功地合成了几个新的取代的噻吩基电光发色团。所有这些发色团都具有类似于FTC的结构，但它们包含了我们新设计的三氰基呋喃二氢呋喃受体。由于这些受体具有各向异性的结构，所以所有的生色团在广泛的有机溶剂中都很容易溶解。用热重分析(TGA)对这些发色团进行了热分析，结果表明它们在空气中都非常稳定。紫外光谱表明，生色团具有很大的溶致变色效应，这意味着很大的分子非线性。
We have successfully synthesized several new substituted thiophene-based electro-optic chromophores. All of these chromophores have structures similar to FTC but they incorporated our newly designed tricyanovinyldihydrofuran acceptors. Since these acceptors possess an anisotropic structure, all of the chromophores are very soluble in a wide range of organic solvents. Thermal study of these chromophores by TGA shows all of them are very stable in air. UV spectra indicate the chromophores have a large solvatochromic effect, implying very large molecular nonlinearities.
