Highly stable and highly soluble push-pull heptamethine hemicyanines based on the tricyanofuran electron-accepting group can be prepared on a 15 g scale. The compounds display giant second-order nonlinear figure of merit, μβ of up to 31,000×10(-48) esu, and lead to a poled material with a second-order nonlinear response, r33 of 90 pm V(-1) at 1.06 μm.
基于三氰基呋喃电子接受基团的高稳定性和高溶解性推拉型七甲川半菁可以在15克规模上制备。这些化合物展现出巨大的二阶非线性品质因数，μβ高达31,000×10(-48) esu，并导致一种极化材料在1.06μm处具有90 pm V(-1)的二阶非线性响应r33。
