Article abstract of DOI:10.1016/j.tet.2013.03.027

Two series of push-pull systems bearing dithienothiophene or thienothiophene as (part of) π-conjugated spacer have been synthesized. These compounds combine high second-order molecular nonlinearities with good thermal stabilities, showing one of the thienothiophene (TT) derivative the highest μβ₀ value found for a 4H-pyranylidene-containing merocyanine.
