Abstract

Some new polymethine dyes of the cyanine and merocyanine series, containing thieno[2, 3-b]thieno[2, 3-b]pyridine-4 and thieno[3, 2-b]-thieno[2, 3-b]-pyridine-8 groups are synthesized. Replacement of the vinylene group by a sulfur atom in the condensed benzene rings of the 5, 6-benzoquinoline-4 group in dyes which are derivatives of this base, results in a marked hypsochromic shift of the absorption maximum of the corresponding dyes.
