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, r 33 of 90 pm V −1 at 1.06 μm
